Backup & restore iscsi_lun_backing_store on RNDU2000
Hello guys, I need to wipe all data from my drives + do a factory reset and I'm wondering if I can just copy the iscsi_lun_backing_store file and restore it after wiping. Do I have to configure ...
I finally got some time to make it work.
Regarding main topic, just for the record: like kohdee said, exact LUN config is needed. Then it's enough to just copy iscsi_lun_backing_store and .serial_number. After this operation i've noticed that the free space diminished twice the size of my LUN. Unassigning the LUN and assigning it back to a group did the trick.
As for the other data, it wasn't so straightforward. In my case, despite the fact my backed up readynasd database file was quite large, for some reason, selecting data from any of its tables returned zero rows.
Copying my old ._share/ and /etc/frontview/*/Shares.conf did not work either. They were overwritten by defaults on each reboot - even after inserting proper data into db.
I wasn't up for creating btrfs subvolumes (thx kohdee for the info, I wouldn't come up with that) manually, so I had to create all the shares from frontview and then do update/insert on db.
I'm not sure what settings you're concerned with losing by not copying the ._share folder. There isn't much config there except snapshot configuration and maybe the iSCSI LUN comment.
Settings like shares configuration (SMB valid users, NFS and AFP config, etc) but I assume it will work after copying.
Most important for me is whole OwnCloud config which should work too, at least I hope it will :smileywink:
