iSCSI issues
hi
I have had this unit in production for a few years now. I used it as an iSCSI target for a network backup. now the issue in the last few months that has happened is that all my backups have fail...
You may delete snapshots in NAS admin GUI,
Steps:
1. Login NAS admin GUI,
2. Open Shares=>Snapshots page,
3. Click Shares or iSCSI LUN, you will see all snapshots in the Share/LUN,
4. Select Share/LUN and right click, delete button will shown, then you can delete snapshots you selected.
if you don't want to use snapshot, then you can disable in Share/LUN's setting,
Go to Share's page in NAS admin GUI, then right click a Share or LUN, open settings page, there is Snapshots settings.
You may set smart snapshot to Never.
Download the log zip file from the web ui. Then start by looking at the SMART stats in disk_info.log. Perhaps look in the some other log files for clues on what's going wrong (system.log and kernel.log would be reasonable places to start).

starts at 300MB/sec then drops to nothing and just hangs the PC.
Gigabit ethernet only carries about 110 MB/sec, so this starting value is caching in the client, and not a real speed.
ok
so I had reply and I thought I replied but it never made it here for some reason.
anyways the error I had are as follows,
Volume: Less than 5% of volume data's capacity is free. Performance on volume data is degraded. To improve performance, you must add capacity.
so what I did was delete the snapshots to the iSCSI and its working but the error is still at 10% but its working. so my question is this.
NAS has 4 1TB drives in a raid5, so 2.7TB total
I have a
iSCSI connection that is 2.3 TB in two drives. 2TB/1.7TB free and 350GB/ all free
SMB share thats 275GB/175 GB free
I dont understand the snapshot features and where does it store it? I can lower the iSCSI volume as I'm not using much of it .
what do you recommend?

Another option is to switch to Custom Snapshot. Then you can set the retention (either by number of snapshots or by age). I found that manages the snapshot space for me. Generally I use 3 weeks retention on most shares, though of course the space needed depends on how much "churn" there is.
Also, I suggest running the balance function regularly (using the maintenance schedule in the settings wheel). Running defrag will increase the snapshot space needed, especially on your iSCSI LUN. So if you keep snapshots enabled on the LUN, you should keep that in mind.
