ZFS Guest Storage Help

[thestupidone]

Hello,

I have come to a situation where I need to mount a ZFS dataset that contains a guest storage block as Read/Write. I can not seem to be able to manipulate the files I need to rescue myself. I have tried using `zfs mount -o remount,noatime,rw rpool` to set the permission I need then mounting using `mount /dev/zd0p2 /media/windows/' I have even tried using the -o rw option, but, to no success. Can anyone give me some pointers?

For context, my guest is running Windows Server 2019, and I need to get a file changed to rescue an admin account.

That is normally the way to go it the zvol (zd0p2) is the correct one. What error do you get? I suppose some errors mounting due to not clean?

Besides getting the actual error to see what can be done, consider that you can also access VM disks stored on a ZFS pool via /dev/zvol/<pool>/<optional datasets>/vm-....-part.... They are symlinks to the actual /dev/zdX device paths, but match the output you get from zfs list.
