Hello everyone: In the process of upgrading lustre 2.15.3 to 2.16.1, I found
that the mount option "discard" is not working, can someone help me out? In
both environments, the "mount -o discard" option is used when mounting. The
operating environment is as follows: lustre 2.15.3 : centos7 + kernel 3.10,
lustre 2.15.3 mount command output>> >> /dev/sdb on
/mnt/lustre/node/00000cACCFDS09a0 type lustre_tgt
(ro,svname=fs153-OST0000,mgsnode=192.168.204.154@o2ib:192.168.204.155@o2ib,osd=osd-ldiskfs,errors=remount-ro,
noacl,discard) << lustre 2.16.1 : rocky9 + kernel 5.14, lustre 2.16.1 mount
command output: >> /dev/sdb on /mnt/lustre/node/000030ACCFDS0cc0 type
lustre_tgt
(rw,svname=fs203-MDT0000,mgsnode=192.168.203.100@o2ib:192.168.203.102@o2ib,osd=osd-ldiskfs)
