...you know if this is possible? I noticed that under the Centos 4.92 beta, RAID 5 is an option but for some reason RAID 10 is not listed. There does appear to be a RAID 10 module.... /lib/modules/2.6.9-42.0.8.ELsmp/kernel/drivers/md/raid10.ko More info I found here: http://cgi.cse.unsw.edu.au/~neilb/01093607424 Many thanks for any help on this; I hate to buy hardware raid controller if not needed....

...ecific knowledge of btrfs in mountd. This is unfortunate. To ensure smooth handling of this and possible future changes in uuid generation, we add infrastructure for multiple different uuids to be recognised on old filehandles, but only the preferred on is used on new filehandles.

...get written to disc at much the same time (hence the "multiple 1 requests"), but the old buffer hits the disc second and so corrupts the filesystem. The bug I found was specific to data=journal mode, and this certainly has more options for buffer aliasing. Were you using data=journal? NeilBrown

...lay to a resync. The previous long sleep (1s) has proven unnecessary, even very short delay brings performance right. The change also applied to raid1. The problem has not been observed on raid1, however it shares barriers code with raid10 so it might be an issue for some setup too.

Various coding style fixes checkpatch warns about. The goal is not to be 100% checkpatch compliant, but to have more consistent coding style. As this is a trivial patch serie, will land in 24 hours in klibc git, unless of course ml review hits a bugger. Checked with size(3) that the generated kinit, fstype, ipconfig and nfsmount are the same. maximilian attems (4): [klibc] ipconfig: reduce

...me. raid5 tries to apply them in the same order that they were received, but I don't feel confident that means that the *right* thing is happening. These were happening with 2.4.16, but the incidence seems to have increased with 2.4.18 (though that isn't a very strong observation). NeilBrown

...age against what is stored in the quota file. Any difference that is found is logged. If the same difference gets logged 3 times in a row, I correct it. The Assertion failure, which has now happened twice, corresponds with running this program.... so I might not run if quite so often any more. NeilBrown

...ing "sync" as much (I currently run it every 5 minutes which isn't needed any longer (it's a long story:-)) but that doesn't fix the bug. My guess is that ext3_sync_dquot doesn't need ext3_journal_start at all but that isn't a well-informed guess. Help appreciated. NeilBrown

...would be keen to here how this patch affects things. The corruption that I see that I blame on this problem is directories begin overwritten with what looks like file contents and in one case (which required 90 minutes downtime for a fsck) some indirect blocks being over-written by file contents.

...work, but is hardly elegant. I'm not in a position at the moment to spend time testing whether the inefficacy of bdflush is ext3 specific or applies to ext2 as well. I may try that next week (we have a long weekend coming up). If it applies to ext2, it could be a showstopped for 2.4.19.... NeilBrown

...ter the rebuild finished, I got an ext3 error (see log below) and the journal aborted, and then nfsd Oopsed inside ext3.
