Solaris10 UFS virtual Disk to TrueNas

[martin12]

Hello together,

we want to migrate existing virtual disks from our virtual solaris 10 server to the truenas. currently we use the virtual solaris 10 server to share data via nfs to a (unfortunately) very old solaris sparc server. we are bound to this server.

now the question is how to migrate the existing UFS data disks (virtual disks) to truenas or how to migrate them in the best case?

- we have assigned the virtual disks to the virtual truenas, we can see them under storage -> disks.
- via storage -> disk import we do not see any disk to choose from.
- using shell we can mount the disk (mount -t ufs -o ufstype=sun /dev/sde1 /mnt/solaris_disk, but then we don't see acl permissions anymore - the question now would be how do we get the data migrated to truenas with all possible attributes (acl, permissions, symbolic links, etc)?

maybe someone can help me?

In all data migrations, I found it easiest and safest to copy data from old systems to the intended new target. The newly copied data can then ve verified/checksum'd to ensure nothing was lost. Have you tried loading data from the UFS disks into TrueNAS via other means? NFS, SFTP, etc.

Since Solaris and UFS are highly supported in BSD, you may have better luck using Core instead of Scale if you need to handle UFS disks often.

i tried cp but it takes forever over nfs (about 1tb of data).
surprisingly it seems to be quite fast via rsync, via this path softlinks and acls are still available.

Unfortunately we are facing other problems, we may still be testing this with the truenas core.

for now i will close this post though, as the problem can be worked around with rsync.
