Hello lustre folks, We have failed ost i have done the below steps. 1) the data has been copied to share location via rsync. 2) deactivated on the MDS with the command lctl set_param osc.lustre-OST001d-*.active=0 3) unmount the ost from oss. 4 ) formate with this command mkfs.lustre --ost --index=29 --replace --reformat --fsname=lustre --backfstype=ldiskfs --mgsnode=10.19.4.132@o2ib /dev/sdd Now when i am trying to copy the data back to the ost it give me the below error. rsync -av --progress /mydata/ost001d/CONFIGS/ /mnt/ost29/ sending incremental file list rsync: ERROR: cannot stat destination "/mnt/ost29/": Not a directory (20) rsync error: errors selecting input/output files, dirs (code 3) at main.c(634) [Receiver=3.1.2]
lustre version is 2.12.6 . below is another output, is it normal behaviour ? mount | grep lustre /dev/sdb on /mnt/ost27 type lustre (ro,context=unconfined_u:object_r:user_tmp_t:s0,svname=lustre-OST001b,mgsnode=10.19.4.132@o2ib ,osd=osd-ldiskfs,errors=remount-ro) /dev/sdc on /mnt/ost28 type lustre (ro,context=unconfined_u:object_r:user_tmp_t:s0,svname=lustre-OST001c,mgsnode=10.19.4.132@o2ib ,osd=osd-ldiskfs,errors=remount-ro) /dev/sdd on /mnt/ost29 type lustre (ro,context=unconfined_u:object_r:user_tmp_t:s0,svname=lustre-OST001d,mgsnode=10.19.4.132@o2ib ,osd=osd-ldiskfs,errors=remount-ro) regards, ihsan
