keyvin posted:So, I should compile a custom kernel without all that garbage red hat enables by default? your kernel should have stable APIs and leverage OO where it makes sense (say in drivers & storage management) so you don't even need to recompile if you want to use a feature, but if you don't it's not even loaded of course this would enable closed-source drivers so it's important for the kernel to change things up a little every now and then (like the order of properties in some data structures).

maybe i am dumb but why would you want RAID in software ala ZFS or BTRFS all my servers have a hardware raid controller already

so you run your software raid on your ec2 micro instance or whatever which is backed by SANs already in some kind of RAID like configuration? so the benefit is?

btrfs is worth it unfortunately you have to janitor it still. e.g. that freespace issue, and balancing, and scrubbing...

I'm sorry, I still can't imagine a statistically significant cost in a hypothetical bizarro world where you were forced to have just the poo poo needed to boot on barfs. I mean, now that we figured this out, can we just say barfs isn't canon? eschaton posted:SysV fanfic Mods, can I get a user name change please?

Captain Foo posted:why is xfs better than ext4 it scales better than ext4, has roughly equivalent performance, and is imo more robust. I'm not one to sperg out about filesystems, but a few years ago I had an ext4 filesystem that blew up, wasn't able to fully repair it, reformatted it to xfs and have had zero issues since.

last time i used XFS it would reliably zero out every file that was open in the event of a system crash. then again this was back when kernel 2.4 was new, but it kind of left a sour taste in my mouth.

and oracle literally sells a $250k filer that is completely handled by zfs. its crap but i think youre understating the usefulness. this isnt 1998 where running software raid is an enormous performance hit

A few days ago i bought a pair of 1TB laptop sized NAS disks (this is apparently a thing) to put into the small linux that lives under my couch turns out the small linux that lives under my couch can't use both of them at once, even though its mobo has two SATA ports. because i've also got an mSATA SSD installed in it and three SATA drives are just too much to handle man  the other mini PCIe slot has a wifi card turns out wifi doesn't work very well inside a case made of metal, although i managed to snake an external antenna out of the case so it works ok now i guess mostly i keep it around as a monument to my shame Sapozhnik fucked around with this message at 16:20 on Jan 9, 2015 |

btrfs is great, i use it on everything, having boot-time snapshots of everything has come in handy more than once software raid is great for single-machine filers, i really like the idea of rebuilding the data after a disk is replaced instead of rebuilding the entire block device containing a filesystem that might only be 30% used srs question: bit flips in reading data are rare but can and do happen, what do you do with a RAID 1 where the two copies disagree? i assume most RAID 1 implementations just read one of the two copies to give any data the OS asks for but if you do a consistency check or something, what happens with btrfs or zfs the answer is "the copy with the correct checksum is used to repair the other one" which is neato

but it's still useful, anyway. I know ur just being a fat contrarian baby but how would you do lvm on cloud instances? Are you just going to stripe the data across the pvs without any redundancy? Is everyone just supposed to buy a netapp?

In an age where tons of poo poo depends on software replication like gluster/drbd/hdfs/ocfs it seems like a retarded neckbeard anachronism to be against mdadm. But it's bsd were talking about and retarded anachronisms are the name of the game. I mean he's obviously not arguing in good faith since software raid is one of zfs' killer features and he's a Solaris fanboy
