Unable to access GPT disk partitions - No such file or directory

Hi, looking for some advice to get some data back.

I've had a FreeBSD 13 system (upgraded over the years from several previous versions) on a VMware ESXi server suddenly loose access to its UFS filesystems.

I cloned the disk image in the VMware server and have attached it to another FreeBSD 13 virtual machine to try to recover access to the data (I have old backups on a separate ZFS filesystem, but I'd sure like to recover the current filesystem). There are no kernel messages about problems with the virtual disk other than the expected boot messages:

da2 at mpt0 bus 0 scbus2 target 2 lun 0
da2: <VMware Virtual disk 1.0> Fixed Direct Access SCSI-2 device
da2: 320.000MB/s transfers (160.000MHz, offset 127, 16bit)
da2: Command Queueing enabled
da2: 81920MB (167772160 512 byte sectors)
da2: quirks=0x140<RETRY_BUSY,STRICT_UNMAP>

gpart shows its info:

The /dev entries look OK to me:

crw-r----- 1 root operator 0x7b Sep 13 14:01 gpusrfs1

However, any attempt to access the /dev entries fails with "No such file or directory":

$ sudo fsck /dev/da2p2
Can't open /dev/da2p2: No such file or directory
$ sudo fsck /dev/da2p4
Can't open /dev/da2p4: No such file or directory
$ sudo fsck /dev/gpt/gprootfs1
Can't open /dev/gpt/gprootfs1: No such file or directory
$ sudo fsck /dev/gpt/gpusrfs1
Can't open /dev/gpt/gpusrfs1: No such file or directory

I've never had an issue like this before and I can't find anything using Google searches that resolves access to these disk devices. Any ideas?

Thanks,
Guy Helmer, Ph.D.

i don't think it's FreeBSD problem at all.
Can you do dd from da2 or da2p2 to /dev/null?
Post by Guy Helmer
$ sudo fsck /dev/da2p2
Can't open /dev/da2p2: No such file or directory
$ sudo fsck /dev/da2p4
Can't open /dev/da2p4: No such file or directory
$ sudo fsck /dev/gpt/gprootfs1
Can't open /dev/gpt/gprootfs1: No such file or directory
$ sudo fsck /dev/gpt/gpusrfs1
Can't open /dev/gpt/gpusrfs1: No such file or directory
I've never had an issue like this before and I can't find anything using Google searches that resolves access to these disk devices.
Any ideas?
Thanks,
Guy Helmer, Ph.D.
Hi, Wojciech, thanks for the response - appreciate any assistance. dd seems to be able to read OK from the devices:

$ sudo dd if=/dev/da2 of=/dev/null bs=4096 count=1000
1000+0 records in
1000+0 records out
4096000 bytes transferred in 0.109224 secs (37500992 bytes/sec)
$ sudo dd if=/dev/da2p2 of=/dev/null bs=4096

$ sudo dd if=/dev/da2p4 of=/dev/null bs=4096 count=1000

Maybe not relevant to the problem, your opening post mentioned FreeBSD 13 systems alone.
Right, I had attached the broken virtual disk to a FreeBSD 12 VM I had available on the same VMware server to research and attempt to recover the filesystems. I've since updated this working VM to 13.2 and I'm getting a bit more informative error messages out of tools like fsck_ufs.

It's looking like either something trashed the superblocks, or the partition offsets were changed.

It's quite a mystery at the moment.

Regards,
Guy
