Hi All,
Is there any way to figure out what exactly btrfs-transacti is chugging
on? I have a few file systems that seem to get wedged for days on end
with this process pegged around 100%. I've stopped all snapshots, made
sure no quotas were enabled, turned on autodefrag in the mount options,
tried manual defragging, kernel upgrades, yet still this brings my
system to a crawl.
Network I/O to the system seems very tiny. The only I/O I see to the
disk is btrfs-transacti writing a couple M/s.
# time touch foo
real 2m54.303s
user 0m0.000s
sys 0m0.002s
# uname -r
4.12.8-custom
# btrfs --version
btrfs-progs v4.13.3
Yes, I know I'm a bit behind there...
-Matt
