[SOLVED] XFS file-restore

mhmm ok one thing you can try though is the following:

start a file-restore, try to open a disk

then run:
Code: 
ps ax | grep file-restore

and post the output here

this should show you a single process with an argument that contains 'file-restore' in the '-kernel' parameter of the restore vm
(it'll probably also show the 'grep' command itself, ignore that)
note the first column (the PID of the vm)

now go into the directory: '/proc/<PID>/fd'
where <PID> is the pid of the vm from before

and post the output of 'ls -lh'

thanks

Hi!

I am trying to open the disc drive-scsi1
and get the error:
proxmox-file-restore failed: Error: mounting 'drive-scsi1.img.fidx/part/1' failed: all mounts failed or no supported file system (500)

I am trying:
root@cn4:~# ps ax | grep file-restore
3126786 pts/1 S+ 0:00 grep file-restore
root@cn4:~#
does not find... :(

But if I am trying to open the disc drive-scsi0 (on the same VM but with ext4)
all works:

scsi0.png


in CLI via proxmox-backup-client map... this drive-scsi1 (with XFS) work too.

---
Best regards
Gosha

you are definitely on the wrong node then... the file restore starts a vm which must have that in the arguments...
 
does it work with a different vm ?
 
also please check the node where your browser connects, not the node you have selected...
