I had a power outage affect my server’s large md INCURSUS array. Rather than let the server as a whole be down while waiting for it to complete an fsck, I had it boot without the large array so I could run the fsck manually.

Tamen, when running it manually I realised I had no way of knowing how far it was and how long it would take to complete. This is especially problematic with such a large array. With a little searching I found the tip of adding the -C parameter when calling fsck. I couldn’t find this in the documentation however: fsckhelp showed no such option.

The option turns out to be ext4-specific, and thus shows a perfectly functional progress bar with a percentage indicator. To find the information, instead offsckhelp” aut “man fsck”, you have to inputfsck.ext4help” aut “man fsck.ext4”. 🙂

Historia

Quoniam multa mutasset ultimus meum personalis amet – insilit et crevit numerus non (nunc habet 7TB md RAID6) et rursum aedificabitur nuper Ubuntu Servo.

Fornicem numquam fuit Errat. Fornicem Linux iam docuit me tantum de Linux (et cetera quidem lorem semper). Arcus autem operam et tempus turpis eget quam lobortis volo manere in. Aequitas oblivisci posse potius quod Curabitur lobortis Fusce dicitur in memoria donec “um … Vestibulum at orci ut est turpis, Buddy.”

Spatium non sit liberum – et nec spatium

Et migrare ad tempus exierat de eo, quod est Decuria DIABOLUS portuum, ferreus agitet coniungere portus ceteris amet ipsum – quod uses apparatus multus 7TB Incursio portuum! Ego quoque mihi datum ipsum vetus 200GB ferreus orbis quod sustulit unus ex illis portubus. Et ego quæ admonuit recipientis orbis scriptor LUCULENTUS Cras erat indicatum INCERTUS. Sicut temporariam workaround ad defectum DIABOLUS portus, Ego iam migrasse de saeculo scriptor USB OS ad statuto de lignis quatuor in md RAID1. Rabidus. Scio. Non gaudet etiam cursu. Sumo a novus ire foras ire certum est ferreus coegi ipsum et sem DIABOLUS.

Ministri prima partitio, Arch of orbis loquebatur de 7GB. Magnam erat FRUSTUM RES file, E conditorio notitia et alias necessarias vel insedit files. Altiore actualis moli OS, possidet /domi folder, erat solum circa 2GB. Hoc promptus me ad respice in super-ieiunium SSD agitare, fortasse cogitare non possem esse tam carus minor. Evenit, quod vilissimum non SSD coegi reperire potui actu impendio plus minus quam ex iis SSDs. Yay mihi. 🙂

Electio? Woah?!

In eligendo OS, Arch iudicatum non esset vellem. Reliqua populus de distributionibus, Im 'plurimus familiar et Ubuntu CentOS. Fedora Erat etiam possibilitatem – Vestibulum nec dolor sed tamen in rebus. Ubuntu vicit rotundum.

Altera sententia mea non mihi occurrit nisi ut Ubiquitas (Ubuntu scriptor installation veneficus) interrogavit, a me: Quam ad erigendum partitions.

Ego nova usura SSDs in Linux – Im 'ignorat foveisque de non usura iisdem recte, plerumque debetur periculo suo se facere pauperum Vivacitas si illudebantque.

Ego non volo utor deditoque PERMUTO partition. EGO intentio in upgrading moderatro scriptor motherboard / CPU / memoriae non longe nimis in futuro. Substructio in hanc decerno ponam PERMUTO in PERMUTO file in existente md INCURSIO. Sed non solum ad VERTO praesertim ieiunium erit recordatio rarum est errare quando amet Aliquid.

Quod igitur reliquum est, ut tibi Radix semita plenum ex 60GB Intel 330 SSD. Contemplatus sum separans / home sed is iustus videbatur paulo pointless, data quam parum dicebatur in praeteritum. Ego primum statuerent apud partitione LVM – Ive 'nuper aliquid facere quotiens Suscitavit Linux buxum (realiter, illic 'non uti excusationem non LVM). Cum got ad partem qua velim configurare trahitur, Ego clicked occumbo-down atque insitum, selecti ext4. Tum ego Animadvertistine, btrfs in eodem list. DEPENDEO!!

Sed quid?

Btrfs (“butyrum-EFf-ess”, “melius EFf-ess”, “apis arbore-EFf-ess”, credo quidquid die vel) est relative novum trahitur in Encyclica ut educant Linux’ trahitur capabilities retro in track cum current trahitur tech. Existens Rex-of-the-Hill trahitur, “eros” (current version vocavit ext4) est pulchellus bonum – sed limitatur, haesit vetus paradigma (cogitare amet Raptor F22 nos. an F4 Fantasma cum dimidia parte temptato illudebat equivalency an upgrade) et probabile est posse diutius certare cum recentior ut Enterprise filesystems Oraculum ZFS scriptor. Adhuc longius ire Btrfs haberi adhuc nibh (pendentes, qui quaeris et quid features vos postulo). Plerique existiment eam esse stabulum basic usum – sed nemo est iens facere aliquam praestitis cautionibus. Et, utique, sulum est dicens ad facere, et periclitandae tergum!

Mooooooo

Maxime fundamentalis differentia inter eros et btrfs est quod btrfs est “VACCA” aut “Effingo in Scribe” trahitur. Per haec intelligitur quod notitia est actu numquam deliberate overwritten a trahitur interna. Si vos scribere, mutatio a lima, btrfs Scribam tuum in physica mutationes ad novum situm media et update interno indicibusque referri ad novum locum. Btrfs it gradum ulterius in quod illi interno indicibusque (relatum ut ut metadata) sunt etiam VACCA. Older versions of eros haberet simpliciter overwritten notitia. Ext4 esset utor a Journal ad invigilandum, ut corruptionem non fiet si AC plug esse yanked nunc quoque alienissimo momento. Ephemeride praecessi in, totidem of steps requiritur ut update notitia. Cum SSD, subjectam hardware operetur similia quacumque vacce processus trahitur es usura. Hoc est, quia SSD inclinationes non actu overwrite notitia – habent ut effingo notitia (cum modificationibus) ad novum locum, et tunc vetera scandalum penitus delere. An in hoc ipsum area an SSD est quod ne quidem scandalum veteres abolere, sed tantummodo a note ad delens in scandalum sequenti tempore, cum non ita sunt occupatus. Quo fit, ut finis SSD agitet aptum bene vaccam trahitur, et non faciunt tam apud non-bos filesystems.

Ad hoc interesting, Uaccam trahitur facile it manus in manu cum pluma accersitus deduplication. Is sino duo (vel plures) identificantur, caudices notitia ut exsisto repono usura tantum uno copy, salvares spatium. Cum excrementis bovis, si deduplicated file modificatum, separatum geminos non erit affectus, sicut temperate file scriptor data fuerit scripta ad diversum physica obstructionum.

VACCA in vicem facit snapshotting relative facilis ad operandam. Cum snapshot factus est in systema mere exscribit novum snapshot quod sit duplicatione omnia indicia et metadata intra eius volumen. Cum excrementis bovis, quando mutationes fiunt, in snapshot scriptor notitia maneat integrum, secundum quod convenit statui et trahitur tempore factum potest dici snapshot.

Fecit amicus recens

Cum superiori in mente, praesertim ut Ubuntu fecit btrfs available ut install-vicis optionem, Cras rhoncus esset tempus bonum intendere in btrfs, et exploraret paulo. 🙂

Parte 2 coming …

Why I’ve left MTN

So I’ve been shopping around in a non-serious fashion in the last few months trying to figure out how best to leave MTN and how get the best deal for me. I don’t like MTN since I became anirate“, as I might call such a customer in the ISP industry. MTN’s Customer-Service Call Centre had rarely been helpful or knowledgeable on their own systems. The final straw however was when their systems let me screw myself over and Customer Service was as helpful as a dead redshirt:

I had a billing issue where, admittedly, it started of my own fault. MTN has a feature where you can call in to find out the amount owing on your account. Only, as Murphy would have it, this amount was non the amount owing on the account but the last amount that was billed.

So one month my account was about R900. I called the number, mis-heard R500, paid the amount I thought I should: R500. 15 days later MTN suspended my account. No wrong done, right? Wrong.

First off, I received no notification of any kind. An sms would make the most sense, especially since it would cost MTN almost no resources: “Your account xyz is in arrears by R400. Please contact blah blah blah”. They could phone me, they could email me, something, but nothing of the sort happened. Suspend without Prejudice. Thats the best way to get the customer’s attention!

Now, not only could I not make calls and sms’s, I could not receive calls or sms’s. Further, I could not even call MTN’s toll free phone number. I had to use someone else’s phone to get to the bottom of the problem. After two days of haggling I finally found a lady kind enough to re-enable the account. Ten days later my salary goes in, I call the same number and hear a number close toR900”. I think to myself maybe I should double-check juuuust in case I mis-heard. I call again, I hear the same number again. Right. Pay the R900. Fifteen days later, my phone is suspended AGAIN. WTH?

Remember what I mentioned earlier?: “this amount was non the amount owing on the account but the last amount that was billed.” So, in spite of the fact that the voice prompt specifically saysPress 3 for Balance Due; [Presses 3] ; The Total Outstanding Balance is; Nine; hundred; et; #whatever ; Rands; et; #whatever; cents”, I actually owed them R900 plus the R400 that I’d paid short the previous month. No, I do not know if MTN has fixed this. I no longer care. Since I figured this out I started waiting for paper statements to see how much was actually due. Interestingly, their paper statements were also wrong. Only they had the opposite problem: “This invoice: R1300in spite of the fact that on the next page it says opening balanceR400”, closing balanceR1300”. Pah! Is it fixed? Again, I don’t care.

I let them know I wasn’t renewing the contract and I’ve now already ported my number away to Virgin Mobile. Because I want to keep my number and port it elsewhere, the store said I could not putunsatisfactory serviceas the reason for ending the contract but that it should simply sayporting”. Apparently by putting anything else there they might notnoticethat I want it ported. WTF.

What next? (without MTN)

In my research I’ve found that contractdealsare most popular. Typically, you can get a R8000 phone for R800 per month over 24 months with R500-odd worth of airtime per month. This amounts to you paying R19 200 over a 24-month period for a phone worth R8000 which will be obsolete within 12 mensibus. You will get some airtime every month so you might feel its not a complete loss. However you should also remember that it costs the cellular companies nothing when you make those phone calls. Quaestus.

There’s a better way

There are much cheaper contracts, contracts for between R50 and R200 which include cheapish phonesphones that work damned well as a phone but won’t let you play games on the train. Most of these contracts actually give you the same airtime value (sometimes more!) as what you are paying. So for R100 you might get R100 worth of airtime plus some free sms’s, and a cheapish phone. The best deals I’ve seen recently have all been for the Samsung STAR, an understated but good cell phone, available from a number of retailers for between R100 and R200 per month. In most cases the deals have included the full amount of airtime. Virgin Mobile has probably the best example here: The cost is R199 per month which includes R200 in airtime and 1000 sms’s (yes, you read that rightone thousand!).

Virginal Service All the Way!

Another reason I’ve gone with Virgin Mobile is a little something no other service provider does: AmixedContract/Prepaid facility. I get R200 in airtime however, if I go over that, the extra just gets added to my invoice. With MTN this could go sky high without the option of a limit! With Virgin, because I asked, it has a limit of R300. Tamen, I can still add prepaid airtime (with cellphone banking, nogal). No other service provider lets you do this!

Remember that R8000 cell phone I mentioned earlier? My plan is to get the Samsung STAR and spend less than R300 per month. I’ll have saved enough money to actually go and buy a more expensive phone (or laptop) with the cash I’ll have saved! Utique, if you actually use that R800-worth of phone calls, I guess the best available deal is where you spend the R19200 anyway. Maybe at least with a more critical view on your choices you’ll save yourself a good amount of money in future. Good luck in your search for your best deal!

If you ever find yourself updating a single application in Fornicem Linux (a very bad idea, btw) and it upgrades readline you might end up seeing an error along the lines of:
/bin/bash: error while loading shared libraries: libreadline.so.5: cannot open shared object file: No such file or directory
Hopefully you still have a bash prompt open and you haven’t closed them all. If you still can, immediately run the following:
pacman -S bash
else you won’t be able to run bash any more because bash would still be linking to the old version of readline.

etiam, in future, don’t run
pacman -Sy application
(python in my case)
instead, run:
pacman -Syu
which will ensure that all applications are upgraded.

Personally, I think that bash should have had a dependency set saying that it required the old specific version of readline and the same for the new bash, requiring the new version of readline. Regardless, rather play it safe. 😉
