Advice setting in fstab
bash99 opened this issue · comments
Hi, Kazuhisya
I found those settings is needed for a large cache(175G), as it tooks a long time for DWB init from the cache.
x-systemd.device-timeout=1200
my real setting
/dev/mapper/wbdev /data xfs noatime,nodiratime,nobarrier,auto,nofail,x-systemd.device-timeout=1200 0 0
, not so sure for nofail part, but without x-systemd.device-timeout=1200, the system won't boot. I use a safe value 1200, in my server, it' tooks 350 secs for DWB read the cache.

"x-systemd.device-timeout option. This is because the default device timeout is 90 seconds"
Hi, @bash99
Thank you for a good advice.
btw, it takes a lot of time to mount instead of dmsetup create ?
If mount does not take time, x-systemd.requires may be used.
e.g.
/dev/mapper/wbdev /data defaults,x-systemd.requires=writeboost.service 0 0
@kazuhisya
Yes, the time consume is on dmsetup part. So your option maybe better.
Ok, I will add the explanation of this issue to the README later.
Thank you!
