Re: [linux-lvm] strange usage stats for thin LV



Dne 2.11.2012 11:46, Andres Toomsalu napsal(a):
Thanks a lot for a detailed explanation - now everything fits into places :)

Some answers:

1) Filesystem in use is ext4 at all cases
2) Im not using discard option as Im not very aware how to use it  - is it a filesystem mount option for fstab?
3) OS is CentOS 6.3 with RHEL OpenVZ patched kernel (2.6.32-042stab061.2 #1 SMP Fri Aug 24 09:07:21 MSK 2012 x86_64 x86_64 x86_64 GNU/Linux)


So check for 'fstrim' command - it's usage is quite simple, and should be already pretty matured tool.

i.e. you could run it once a week in cron.
