Unable to delete volume

[TNX255]

Hey everyone,

I am trying to set up a new NAS4Free server (version 11.0.0.4 - Sayyadina (revision 3460)), but I ran into a problem. Being new to ZFS, at first I thought I needed to create volumes on top of virtual devices and zpools, so I created one, but after reading more about ZFS I realized it is datasets that I want. Now however I can't get rid of the volumes in the config. Using the GUI I chose them for deletion, clicked on "delete selected volumes", and after the page refreshed I clicked on "Apply changes" ... and then I clicked on it again ... and again ... and again ... and then I started suspecting something is probably wrong

The volumes that I'm trying to delete can still be seen in the Volumes tab normally, except for an error message in the "Size" and "Block Size" tabs ("cannot open 'POOL01/MIRROR-1TB': dataset does not exist"). When I look for errors in the system log there is the following:

Feb 6 21:14:17 XXnas root: zfs destroy 'POOL01/MIRROR-1TB'
Feb 6 21:14:17 XXnas root: cannot open 'POOL01/MIRROR-1TB': dataset does not exist
Feb 6 21:14:17 XXnas root: Error: Failed to destroy volume POOL01/MIRROR-1TB

I've tried the following myself:
- Rebooted the server
- Tried to delete the pool "POOL01" (via GUI)
- Tried to recreate the pool "POOL01" (via GUI)
- Tried to create dataset "POOL01/MIRROR-1TB"; I get an error "The following input errors were detected: 'POOL01/MIRROR-1TB' is already configured as a volume." (via GUI)

I tried duckduckgoing and used the search on the forum but I came up empty. Can anyone help?

Disks -> ZFS -> Configuration -> Synchronize should help you

[TNX255]

Thanks, the Synchronize-function cleared the ghost volumes from the config!

I assume it somehow checks for the actual existence of volumes, datasets, pools and virtual devices against NAS4Free's config database?

I've same problem, but in synchronize "Nothing to synchronize"

post more info, about your pool and sync webgui and your Disks > Management > HDD Management

and post:



Disks > ZFS > Configuration > Current

and

Disks > ZFS > Configuration > Detected

hello,

I can't delete volume.

inas: iNAStorage# zfs get mountpoint

iNASt mountpoint /mnt/iNASt local
iNASt/Backups mountpoint /mnt/iNASt/Backups inherited from iNASt
iNASt/Swap mountpoint - -


Nov 14 17:49:19 root: Error: Failed to destroy volume iNASt/Swap
Nov 14 17:49:19 root: cannot destroy 'iNASt/Swap': dataset is busy
Nov 14 17:49:19 root: zfs destroy 'iNASt/Swap'

can you help me?

the Swap directory don't exist on /dev/zvol/iNASt/

igr4free look at Disks > Mount Point > Management and make sure it is not mounted

does not appear. but yes in ZFS>Volum. but i can’t eliminate it. And also not modify it

[raulfg3]

is your pool imported from other install like freenas?

no.
I wanted to try to create a SWAP volume. I was wrong with the size and it did not let me modify it or erase it.

then, it occurred to me "the fantastic idea" to delete the directory ...

and now it does not disappear from the web menu in disc>zfs>volume, neither in the nas4free main screen that there is a volume called swap.

[raulfg3]

create a new folder named swap in the desired path, and then delete from webGUI ( this time must work).

if still not , you need help from developers to identify the problem ( webGUI or real ZFS)

I have tried it several times, but it always answers me denied. even being root.
Fortunately it is domestic service, it is not critical, and I have been able to restore it with the previous configuration. but it was not the solution he was looking for. I preferred to find the reason or solution hehe

Now when restarting, initially the volume did not appear. I have synchronized and it has left, but at the same time it has created in / zvol / the volume.

at least now it does work
