Redhat EL5 won't boot after adding EXT3 volume via iSCSI

Posted on 2009-04-20
Last Modified: 2013-12-06
I installed iscsi_initiator, connected to my SAN, and then added a 600GB ext3 file system to a Redhat Enterprise 5 server. Now when rebooting the iSCSI volume has not been connected and i receive the error "fsck.ext3 no such file or directory while trying to open /dev/ds_storage"

If i boot the kernel with the emergency switch i can get to a command prompt but since the file system is read only i cannot make any changes to fstab. What would be the proper way of getting this back online as well as connecting the iSCSI storage prior to mounting the FS? Also, should i have created some other type of file system?

    it looks you need to initialise the iSCSI storage before the system does a mount -a or change the fstab to not auto mount on boot then perhaps add a line in rc.local to mount the filesystems, iSCSI should be available at this point.

    How can i make any changes now that the volume only mounts in read only mode? I can edit fstab but it won't save any changes.

    mount -o remount,rw /

    Can you boot into single user mode? S, s or 1.

    This allowed me to get the system back up. A note for others though, iSCSI was hanging on shutdown (noted in other questions) due to an issue with the nic shutting down before the iSCSI cache was flushed, which hung the server. I hit the reset button which cause file system issues (could not find numerous profile entries in /etc). What a pain.
