Move files from Shared Folder to iSCSI LUN then delete Shared Folder

Unread post by SoriceConsulting » Tue Jan 02, 2018 9:53 pm

Have a Synology DS1815 with (4) 10TB Disks and 1 Volume. Total Volume size is 26TB
BTRFS File system, Hybrid Raid (SHR) with 1 disk fault tolerance.

I currently have a Shared Folder setup to store backups of some Server data. Contains about 8.8TB of data.

What I'd like to do is:
> Create an iSCSI LUN, thin-provisioned, that would have a maximum size of all available space (about 26TB)
> Copy all the files from the Shared Folder to the new LUN
> Delete the Shared Folder

Since Volume 1 is currently using 8.8TB and has 17.38TB free, it seems like this should work fine. But, since I'm not all that familiar with how NAS storage works just want to make sure I'm not missing something...

Did you find a solution for this? I have the same problem here.

Thanks.

What problems do you expect? I use iSCSI LUN as storage of SQL databases, LUN is conencted to Windows Server 2012 R2 with SQL Server 2017. backups on daily basis i do to network share folder, synced to another off-site NAS. The only problem i have is that i cannot make app-consistent snapshots of the LUN, which was my prefered way how to make DB backups. Unfortunatelly, Synology does not support such scenario. But current scenario works as well.
DS918+ (4GB RAM, 2x4TB SHR, 2x256GB read/write cache) business, DS916+(8GB RAM, 3x2TB SHR) home, DS213j(512MB RAM, 1x1 TB single, 1x 500GB single) off-site backup

Why? (change to LUN)
1 disk fault tolerance bad idea with 10TBs

Locked
