Description

On April 6, 2016, we noticed one particular file system getting many of the following errors, which corresponded with user job failures:

Kernel: LustreError: 191208:0:(vvp_io.c:1086:vvp_io_commit_write()) Write page 82782 of inode ffff8803a8fd06b8 failed -28

'lfs df' showed the filesystem was only 76% full; however, it also showed that 32 of the 80 OSTs were 89%-90% full. Since deactivating those 32 "near-full" OSTs on 4/6, we haven't seen the problem on that file system.

Consequently, we are now seeing the issue on another file system where OSTs are ~ 90% full.

Looks very similar to what SNL was seeing in LU-7510.

Could you please look into the fesaibility of porting the two mentioned patches to the 2.5 FE branch?

Thanks

Peter

The patches for LU-2049 touch a lot of ofd code, but the code was heavily re-factored in the run up to 2.6 (at a minimum would need LU-3467), and this is JUST the ofd directory. This would be a very complex port, and I would deem very risky.

[Christopher Morrone]

What about the second LU-2049 patch?

[Olaf Faaland]

Do you still intend to merge https://review.whamcloud.com/#/c/22567/ to b2_8_fe?  Looks like it got the reviews you asked for.
