global serialization points in XFS circa 2.6.27?
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.
