Cant change permissions on root dataset

TrueNAS General
1

so the documentation says " You can view permissions for any dataset, but the edit option only displays on the Permissions widget for non-root datasets."

and that seems to be true. except…mine was changed apparently during the freenas days on just one of the multiple root datasets, and its causing an issue with permissions.

my guess is that you used to be able to change them, but not anymore. but mine were changed and its causing me some issues. any way to change it back? or easier to just rebuild that one vdev to start over?

I suppose this is Core? Your signature doesn’t say.

The ownership for a pool’s root dataset should be root:wheel, and its permissions should be 755.

You can do this in the command-line with an SSH session:

chown root:wheel /mnt/<nameofrootdataset>

chmod 755 /mnt/<nameofrootdataset>

Use sudo if you’re not logged in as the user root.

its scale, i forgot to add it but its there now :slight_smile:

ok, so i did that and the result is attached, along with what the other vdevs look like permission wise. any way to get back to that?

thanks for any guidance.

It appears you had previously applied an NFSv4 ACL to the pool’s root dataset path.

You will need to strip its ACL.

@awalkerix, is it safe to strip the ACL with the command-line on SCALE? Any surprise catches?

Depends on the context. If it’s just removing acls from the mountpoint because traversal is broken because of following some terrible youtube advice nfs4xdr_setfacl -b <path> if you’re looking to do something recursive I think it needs to be approached more thoughtfully.

thanks for the guidance

using that i found an article that expanded a bit ie:
“you can edit the local NFSv4 ACL via the command nfs4xdr_setfacl -e <path> which opens a vi editor that you can use to fine-tune the ACL as needed.”

so i used that and fixed the root! that saved me a lot of time.
(note there was no youtube advice done by me, but i didnt originally set this up so…who knows)

anyway, on to my next and hopefully last [known] issue on this box which is similar to this. the other vm (one that i set up unfortunately, but it was for testing vms so no harm) is set to posix for the root vs all other datasets set to SMB/NFSv4. not sure when that happened or if i care, but if i should care, any idea how to change that easily? whats odd is that i have smb shares set up on that dataset and they work, so…

[never mind, it seems this is the new default setting for root datasets]
