MDS read-only
Dear all,
Two of our MDS have got repeatedly read-only error recently after once e2fsck on lustre 1.8.5. After the MDT mounted for a while, the kernel will reports errors like:
Oct 8 20:16:44 mainmds kernel: LDISKFS-fs error (device cciss!c0d1): ldiskfs_ext_check_inode: bad header/extent in inode #50736178: invalid magic - magic 0, entries 0, max 0(0), depth 0(0)
Oct 8 20:16:44 mainmds kernel: Aborting journal on device cciss!c0d1-8.
And make the MDS read-only.
This problem ha...
