A little help here? One OST fails to mount with the following: LDISKFS-fs: group descriptors corrupted! LustreError: 8364:0:(obd_mount.c:1278:server_kernel_mount()) premount /dev/mpath/lun_13:0x0 ldiskfs failed: -22, ldiskfs2 failed: -19. Is the ldiskfs module available? LustreError: 8364:0:(obd_mount.c:1592:server_fill_super()) Unable to mount device /dev/mpath/lun_13: -22 LustreError: 8364:0:(obd_mount.c:1997:lustre_fill_super()) Unable to mount (-22) LDISKFS-fs error (device dm-13): ldiskfs_check_descriptors: Checksum for group 2560 failed (12546!=45229)
I assume running an e2fsck -fy against the OST is the prefered solution, I just want to confirm. 'e2fsck -fn [dev]' gives: Group descriptor 2560 checksum is invalid. Fix? no [...] Group descriptor 2687 checksum is invalid. Fix? no ---------------- John White High Performance Computing Services (HPCS) (510) 486-7307 One Cyclotron Rd, MS: 50B-3209C Lawrence Berkeley National Lab Berkeley, CA 94720 _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
