Good Day! Yesterday evening around 5:30 p.m. local time, one of my lustre client systems lost one of its two lustre disks. I was not able to remount it, even after a reboot of the client. The mount command returns the following message: [r...@crew01 ~]# mount /crew2 mount.lustre: mount ic-m...@o2ib:/crew2 at /crew2 failed: Invalid argument This may have multiple causes. Is 'crew2' the correct filesystem name? Are the mount options correct? Check the syslog for more info.
And the /var/log/messages file (CentOS 5.1 system using 2.6.18-53.1.13.el5): Jul 16 10:30:53 crew01 kernel: LustreError: 156-2: The client profile 'crew2-client' could not be read from the MGS. Does that filesystem exist? Jul 16 10:30:53 crew01 kernel: Lustre: client ffff810188fcfc00 umount complete Jul 16 10:30:53 crew01 kernel: LustreError: 26240:0:(obd_mount.c:1924:lustre_fill_super()) Unable to mount (-22) The entry in the client /etc/fstab file is unchanged from before: ic-m...@o2ib:/crew2 /crew2 lustre nouser_xattr,_netdev 0 0 This same client uses the /etc/fstab entry "ic-m...@o2ib:/crew8 /crewdat lustre nouser_xattr,_netdev 0 0" This lustre disk is still mounted and usable: ic-m...@o2ib:/crew8 76T 30T 42T 42% /crewdat What is also interesting is that other clients still have access to the /crew2 disk, even though this one client does not. There are no crew2 errors in the MGS/MDS system which serves both of the lustre disks. What has this one particular client lost that prevents it from mounting the /crew2 disk to which the other clients still have access? Any and all suggestions are appreciated. megan _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
