So here is a warning and a plea for help… I hve my EX2 set up with a RAID-1 array using two 3TB drives. I had the entire volume dedicated to a 3GB iSCSI target that was mapped to my server here. All worked great for months.
Then I had an extended power outage. When power came back up, my server could not connect to the iSCSI target in the EX2. I took a look at the device and saw that the iSCSI target list was empty and the device was no longer serving the target! I used SSH to verify that my .img file is still there… The data still exists. But I cannot get at any of it as it is locked away in the image file!
I called into support, fully expecting to have a terrible time getting escelated and bounced around until I might find someone who could talk me through rebuilding the iSCSI target list on the device by editing some config files or whatever… Well, after 3 different calls consuming more than 2 hours, I was told by tier 2 that what I wanted to do was “impossible” and that my only hope was to copy the .IMG file down to a local hard disk and attempt to access it with 7-ZIP or some other utillity that can open ISO IMG files.
Well, that simply is not true. I mean, set aside that I don’t have 3TB free here so I have to go buy a new hard drive to actually do this - or canabalize one of the two drives in the RAID array to manage this… But even if I do that, I am very sure that no app is going to easily open this iSCSI IMG file as it is NOT a standard disk image. I’m fairly sure that my only hope is to get the image off the drives, completely wipe them, use the EX2 to build a new iSCSI target volume with exactly the same parameters as the first one, and then hopefully move the IMG back and overwrite the one that gets created by my intermediate step.
I don’t even know if that will work. Support happily told me that I should have made a backup of my data and that RAID-1 is not really a backup solution. Yea, I know that. And shame on me for using iSCSI which seems to be the root of my nightmare. Had I just used the drive as an SMB share server, none of this would have happened.
So, does anyone know how I might access the data within this image? I mean, i can boot into Linux if that might help me to mount it - I’m not completely familiar with NAS iSCSI implementations and im also not sure what LInux distro the EX2 is based on. I believe that is something I need to know so that I know what kind of IMG this might be?
I dug on google and found one other guy who had this exact problem but his solution was to just blow everything out and go again. I really want to get the data out of this image if I can.
