Hello all,
About a week or so ago I noticed that [btrfs-ino-cache] process was
appearing in the 'top' on each reboot and disk is spinning like crazy for
about five minutes or so. Quite so often this caused X failing to start
because all I/O was busy with caching.
Even after letting it to calm down and seeing [btrfs-ino-cache] disappearing
from the process list, on next reboot it starts all over again.
Here is the fstab entry that I have
UUID=430dca92-9541-4201-0f62-373e30beadac / btrfs subvol=root_subvolume,defaults,noatime,noacl,compress=lzo,inode_cache,space_cache,autodefrag
0 0
inode_cache was always enabled since the FS was created about a year or so
ago, and actually I have never had any problems with it up until recently.
Removing inode_cache option from fstab solves the problem, but I am not sure
if it is the right choice.
I can observe the problem at least in the vanilla kernel 3.10.4 ~ 6 (did not
try older versions)
What could be the reason for such behavior and how to avoid it?
That's odd. Can you apply patches and build kernels so I can try and narrow
down what is happening? Thanks,
Josef
Hi Josef,
Sure, I can do that. I am running archlinux with a vanilla kernel that I
build myself.
Thanks
