I have UNRAID Version: 6.12.6

 

How to increase domains share size?

 

I understand VM's disks are created in the system share: /mnt/user/domains and due to the number of VM vdisks I am near the limit of the domains' share, in fact if I fill it too much the UI becomes unstable, luckily I had the terminal open to remove my last vdisk creation.

 

my system's domains share:

- primary storage is array - with array with ~7TB free

- Allocation: High-Water, included disks: all 

- no secondary storage so no mover

- yet,  in user shares, when i click compute to the domains size the ssd (i only have one for cache) appears under domains, where the array at 11GB free and the ssd have 811GB free, with a size on the array and ssd line of 322GB.

 

I have searched the documentation and forum (and web/AI) for guidance with no joy.

 

Help and assistance would be appreciated.

This suggest there are files outside the share config, and typically you don't want the array for domains, it will be much slower, please post the diagnostics.

domains                           shareUseCache="prefer"  # Share exists on cache, ssd

 

Share exists in two pools, you should move the data to one pool only.

I gather this is the documentation on the how: https://docs.unraid.net/unraid-os/manual/shares/user-shares/#moving-files-from-the-array-to-a-pool-cache ?

I'm learning here so your guidance is appreciated @JorgeB. How do I change domains to shareUseCache="only", which is what I gather is also required for better performance of VMs/Dockers? (couldn't find this)

Mover with v6.12 doesn't support pool to pool moves, you can move to the array, then from the array to the other pool.

 

Cache only is the same as just setting primary storage to a single pool with v6.12 or newer.

following a power outage lasting longer than my UPS battery, some of my vdisks for my VMs have gone. Any idea on recovery methods? 

[JorgeB]

Vdisks should not disappear after a power failure, but if they did, best bet is restoring from a backup, assuming one exists.

They have im assuming they suffered being across pool and array as you warned about here, but i cannot find them on both now. Thanks for your response.
