Hi, Our MDT volume went read-only this morning apparently due to a bad directory entry: > Oct 27 09:00:56 mds2 kernel: LDISKFS-fs error (device dm-10): ldiskfs_dx_find_entry: bad entry in directory #85863408: rec_len % 4 != 0 - block=42931201offset=24(24), inode=0, rec_len=2049, name_len=0 Does this indicate a problem with the MDT block device/hardware ? We are using lustre 2.5.29. thanks, chris hunter chris.hunter(a)yale.edu
