Appolgies if Im missing something obvious here. My OSTs are set up in Raid 5 and one of the arrays has a bad stripe so i need to rebuild it. In preparation for this i want to move all the data off of this OST so i deactivated the OST on the MDS and ran:
lfs find --recursive --obd nasone-OST0002_UUID --quiet /lustre | while read F; cp $F $F.tmp && mv $F.tmp $F; done This ran for quite a while and after it finished i ran the find command again to confirm there were no more files on the OST. However if i look at the OSS i still show there are 3.4TBs of used space on that OST2: # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdd 5765425880 5223515676 249043440 96% /mnt/ost4 /dev/sdc 4804519904 3479755816 1080708536 77% /mnt/ost2 Does this make any sense at all or am i missing something obvious here? I was expecting (hoping) to see the used space back to almost zero so does this mean i have quite a bit of lost data? Any help?
