[lustre-discuss] mount option " -o discard " not woking in lustre 2.16.1 mdt/ost

[牛星星]

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 at o2ib:192.168.204.155 at 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 at o2ib:192.168.203.102 at o2ib,osd=osd-ldiskfs) << and logs from /var/log/messages: >> Feb 10 17:44:28 node1-mds1 kernel: Lustre: fs203-MDT0000: mounting server target with '-t lustre' deprecated, use '-t lustre_tgt' Feb 10 17:44:28 node1-mds1 kernel: LDISKFS-fs (sdb): recovery complete Feb 10 17:44:28 node1-mds1 kernel: LDISKFS-fs (sdb): mounted filesystem dd47b0a5-8594-4ebc-9ee2-3213558bf599 r/w with ordered data mode.
