Hi,
I've got an embedded system running a modified 2.6.27 (yes, we're trying
to upgrade) and we're running into a scenario where something is
happening that causes accesses to *all* XFS filesystems to hang or be
delayed for some time.
I know it may be a bit of a stretch since the kernel is old, but I was
wondering if you might have any suggestions as to what I might look at
as far as locks/algorithms within XFS that would affect all filesystems.
In case it matters, the hardware is fairly beefy-- 32 threads of Sandy
Bridge CPU, 64GB RAM, SAS drives, etc.
Chris
