Can you descr= ibe > your setup in more detail? I created this btrfs filesystem on an arch linux system (amd64, quad=20 core) with kernel 2.3.38.1. it is on top of a md raid 5. [root@linuxserver ~]# cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] md0 : active raid5 sde1[3] sdc1[1] sda1[0] sdf1[4] 5860535808 blocks super 1.2 level 5, 512k chunk, algorithm 2=20 [4/4] [UUUU] the raid was grown from 3 devices to 4, and then btrfs was grown to max= =20 size. mount options were clear_cache,compress-force. I was investigating a performance issue that i had, because over the=20 network i could only write to the filesystem at about 32mb/sec. when writing btrfs-delalloc- cpu usage was at 100%. While investigating i disabled compression, enabled space_cache and=20 tried zlib compression, and various combinations, while copying large=20 files back and forth using samba. BTW I tried to change some mount options using mount -o remount but=20 although the new options were printed on dmesg i think that they were=20 not enabled. I got the first error when i was copying some files and at the same tim= e=20 created a directory over samba. After a while i upgraded to 2.6.38.5 bu= t=20 nothing seems to have changed.

It could be because the write went to the wrong spot, or the hardware stack messed it up, or because of a btrfs bug. But, 2.6.38 is relatively recent. I= t doesn't look like memory corruption because the transids are fairly close. When you grew the raid device, did you grow a partition as well? We've had trouble in the past with block dev flushing code kicking in as devices are resized. Samba isn't doing anything exotic, and 2.6.38 has my recent fixes for rare metadata corruption bugs in btrfs. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" = in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 13+ messages in thread

I can remember that as a test (to see if shrink works) i shrank the fs=20 by 1 gb and then grew it again to max size. > > Samba isn't doing anything exotic, and 2.6.38 has my recent fixes for > rare metadata corruption bugs in btrfs. > > -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" = in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 13+ messages in thread
