  To: xfs

hi,

is the following calltrace related to xfs or something else?
it happended during "stress --hdd 20 --hdd-bytes 2g" on a
raid10 volume:

> # cat /proc/mdstat 
> Personalities : [raid1] [raid10] 
> md0 : active raid10 sdd5[3] sdc5[2] sdb5[1] sda5[0]
>       39069824 blocks 64K chunks 2 near-copies [4/4] [UUUU]

maybe this is xfs' way to tell "out of diskspace"? :)

Raoul,

You've exhausted the bio mempool. That is not supposed to happen.

This is a block layer or configuration issue, not an XFS problem.

Jens, have you heard of anything like this recently?

Cheers,

Dave.

Nope, haven't heard of anything like this. But I don't think your
analysis is quite right - if you call into mempool_alloc(), it may
rightfully try to allocate outside of the pool only to fallback to
pre-allocated entries. So the page allocation failure message isn't a
bug as such, just the vm running complete OOM.

Now, if mempool_alloc() returned NULL with __GFP_WAIT set, THAT would be
a bug.
