Old disk where i cant find all the data.

[kk-openbox]

Hey Proxmoxers.

I have moved to a new server a 2 years ago and at that point i tried to move to new SSD also.
Now i turned the old computer on with the old drives that have not been deleted because i know there is some data, that i home still is there.

When i look in the term i see that the 1T drive is almost 75% filled up.

root@kamper:/# zpool list mt
NAME   SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
mt     928G   687G   241G        -         -    54%    74%  1.00x    ONLINE  -
root@kamper:/# zpool status mt
  pool: mt
 state: ONLINE
  scan: scrub repaired 0B in 0 days 00:09:55 with 0 errors on Sun Jul 11 00:33:56 2021

errors: No known data errors
root@kamper:/#

And in the front end in PVE i see the same.


But i only have one disk image on it when i look at



how do i see what else is on that nvme thats filled up with aprox 800gb?

I would first try zfs list -o space to see whats stored on ZFS. As well as cat /etc/pve/storage.cfg to see where the storages store stuff. Maybe df -h to see some other mounted filesystems.

 

[kk-openbox]

It gives the same output with zfs list -o space

root@kamper:~# zfs list -o space

NAS                 250G  1.51T        0B     96K             0B      1.51T

And

root@kamper:/mt# cat /etc/pve/storage.cfg
dir: local
    path /var/lib/vz
    content iso,backup
    maxfiles 1
    shared 0

lvmthin: local-lvm
    thinpool data
    vgname pve
    content images,rootdir

zfspool: mt1
    pool mt
    content images,rootdir
    mountpoint /mt
    sparse 0

zfspool: StorageNAS
    pool NAS
    content images,rootdir
    mountpoint /NAS
    sparse 0

dir: templates
    path /mt/templates
    content iso,vztmpl,images
    shared 0

Maybe the nvme used to be "passed-through" to a truenas VM and hence the drive is a zfs drive.

When i run a fdisk on the drive i get

Device           Start        End    Sectors   Size Type
/dev/nvme0n1p1     128    4194431    4194304     2G FreeBSD swap
/dev/nvme0n1p2 4194432 1953525119 1949330688 929.5G FreeBSD ZFS

But this doen't help me to see whats on the zfs drive..

There should be 686GB of files in "/mt" and its subfolders.
And 942GB of data on that "NAS/vm-101-disk-0" block device.

That is what i was thinking too.

I was thinking that there might be a zfs pool on that drive also, but when i try to do a import i can't see it.

root@kamper:/mt# zpool import
   pool: boot-pool
     id: 15513697974996719685
  state: UNAVAIL
status: The pool can only be accessed in read-only mode on this system. It
    cannot be accessed in read-write mode because it uses the following
    feature(s) not supported on this system:
    com.delphix:log_spacemap (Log metaslab changes on a single spacemap and flush them periodically.)
    com.delphix:livelist (Improved clone deletion performance.)
action: The pool cannot be imported in read-write mode. Import the pool with
    "-o readonly=on", access the pool on a system that supports the
    required feature(s), or recreate the pool from backup.

Check if that pool is actually mounted:
zfs get mounted,mountpoint,canmount mt

Not that you are just looking at an empty mountpoint on the root filesystem as PVE also creates these folder on its own when they don't exist.
