Hi all,
We've having an issue at the moment where an iSCSI connection was temporarily lost on a few VMs running CentOS 6 on ESXi.
The problem is, now that the iSCSI connection has returned, we are not able to remount the drive.
At first the drive is read-only, so I tried '*mount -o remount,rw*' which didn't work (still read-only), so then I tried a '*umount*' (which worked), but now I get the following error when trying to mount it again:
root@server [~]# mount /backup/ mount: /dev/sdb1 already mounted or /backup busy root@server [~]# mount /dev/sdb1 mount: /dev/sdb1 already mounted or /backup busy
I have also tried '*echo "- - -" > /sys/class/scsi_host/host1/scan*' and checked to see if any processes were using /dev/sdb1 or /backup using ' *fuser*' and '*lsof*'.
I know a reboot will solve it, but I'm trying to avoid that as best I can, so I'm wondering if anyone else has any other ideas?
Any help would be greatly appreciated, thanks. :)
Regards,
Kyle Thorne
