Hi, i''ve a big problem, please help me, I''ve a lustre filesystem of about 300 TByte, lustre version 1.8.4 currently i''m using 6 host, the first one mount 1 lun for mgs, 1 lun for mdt and 6 lun for ost the other 5 hosts mounts only ost mgs lun and mdt lun are about 500 GB every ost has the journal in another lun, last week mdt goes full of inodes, 100% used so, we create another lun with about 900 GB of space, the lun was formatted with command mkfs.lustre and we use the rsync command with -Xav option to sync the old and the new mdt, after that we mount the filesystem with new mdt, and if we do the lfs df -i command we can se the right number of inodes and the right space used, but all the files now has 0 byte and if i do "vi" every file is empty. the old mdt lun is corrupted an the e2fsck has erased many iondes, so i cannot use that lun. Is there a way to rebuild mdt catalog from ost or so? please help me!!! Antonio

Hi, When you performed your backup / restore process of your MDT did you follow the manual? Also did you verify that your backup process successfully backed up the EA information on the files? -cf On 09/13/2011 02:05 PM, Antonio Concas wrote:> Hi, > > i''ve a big problem, > please help me, > > I''ve a lustre filesystem of about 300 TByte, > lustre version 1.8.4 > currently i''m using 6 host, > the first one mount 1 lun for mgs, 1 lun for mdt and 6 lun for ost > the other 5 hosts mounts only ost > mgs lun and mdt lun are about 500 GB > every ost has the journal in another lun, > > last week mdt goes full of inodes, 100% used > so, we create another lun with about 900 GB of space, > the lun was formatted with command mkfs.lustre > and we use the rsync command with -Xav option to sync the old > and the new mdt, > > after that we mount the filesystem with new mdt, and if we do > the lfs df -i command we can se the right number of inodes and > the right space used, but all the files now has 0 byte and if > i do "vi" every file is empty. > > the old mdt lun is corrupted an the e2fsck has erased many iondes, > so i cannot use that lun. > > Is there a way to rebuild mdt catalog from ost or so? > please help me!!! > > Antonio > > > > > > > _______________________________________________ > Lustre-discuss mailing list > Lustre-discuss at lists.lustre.org > http://lists.lustre.org/mailman/listinfo/lustre-discuss
