 Posted: Fri Oct 17, 2008 7:36 pm Post subject: Problems with XFS on x86 Gentoo |
 |
|
I often have xfs errors specially during file transfer via NFS to server (xfs partition). After such errors (examples below) I have to restart my server and run xfs_repair which gives me usually some info about corrupted files.
Example output:
| Code: | [462567.973560] Filesystem "sda6": Access to block zero in inode 3257375020 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 329
[462567.983921] Filesystem "sda6": Access to block zero in inode 3257375020 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 32b
[462567.993600] Filesystem "sda6": Access to block zero in inode 3257375020 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 32b
[462568.011638] Filesystem "sda6": Access to block zero in inode 3257375020 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 32d
[462568.013668] Filesystem "sda6": Access to block zero in inode 3257375020 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 32d
[462568.023831] Filesystem "sda6": Access to block zero in inode 3257375020 start_block: 0 start_off: 0 blkcnt: 0 extent-state: 0 lastx: 32f |
Is there any way to track source of this problem? Does anyone had simmilar problems with XFS? How it is compared to ext3 when we think about files corruption?
Thanks for help.

Thanks for reply. Currently I use stock x86 gentoo kernel but I'll look for this patch during 2.6.27 move. Anyway I don't really know where to look for source of problems. I've only found that corruption occurs under heavy hdd usage. Maybe it's power related? I have Via Epia board + 750 GB F1 Samsung drive and 90W fanless PSU.
My xfs_info:
| Code: | meta-data=/dev/sda6 isize=256 agcount=32, agsize=5669187 blks
= sectsz=512 attr=0
data = bsize=4096 blocks=181413984, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096
log =internal bsize=4096 blocks=32768, version=1
= sectsz=512 sunit=0 blks, lazy-count=0
realtime =none extsz=4096 blocks=0, rtextents=0 |
fstab:
| Code: | | /dev/sda6 /home xfs noatime,nodiratime 0 0 |
smart seems to be OK:

are you using 4k stacks?
because 4k+xfs+nfs is a known bad scenario.

yeah, check your kernel config.
