Unable to use Mover to clear cache

Featured Replies

Hello!

 

I'm in progress of upgrade the hardware of my server which includes switching to new cache drives. So I followed SpaceInvaders recent video to temporarily move data from the existing cache to the array. So I disabled docker and VMs, changed the mover action for all my shares to be Cache > Array, but after 12 hours there is still 7.5 GBs on the cache. And there are no more reads/writes on either share. I restarted and attempted again but Mover is now greyed out with still no progress.

 

I attached the list of files that seem to still be in Cache: an empty docker folder for Krusdaser, lots of System files, and an IMG for libvirt. I'm open to moving things manually but I'm hesitant incase something could be lost. Any advice would be great, thanks!

You should check if those files/folders already exist on the array?   Mover will never overwrite an existing file, so if you have a file at both locations you have to decide which one to keep and manually delete the other (typically the older one).   Dynamix File Manager can help with doing this.

Thanks, that's a good callout. I opened File Manager but I can't find exact matches of the System files anywhere on the array, so that might not be the case.

Enable mover logging, run the mover, post new diags.

Got it, I was able to see errors on a few files that definitely were duplicated in back cache and array, so I deleted those manually and Mover continued for a period. It seems stuck again currently, now with 2.72 GBs in cache still. New diags attached.

 

It seems most of the remains files exist within /mnt/cache/system/docker/docker/btrfs/subvolumes/... and a single libvirt.img file. I'm hoping these are OK to move manually or are unimportant and can be deleted. Any advice would be great!

Because of the anonymizing can't see which files have issues, but these will not be moved:

This is important if you have VMs, and the mover should move it, as long as the VM service is disabled and it's not a duplicate file.

Cool, so I could delete the files within subvolumes, and manually move the IMG file if it isn't duplicated?

Yes, that should be fine, docker image/folder can easily be recreated, as long has you have the appdata (and the user templates on the flash drive).
