Xen Orchestra - Permissions Issue - File level restore

DustinB3403

Ok so (office party atm) but did you get your fuse issue corrected?

Danp

@DustinB3403 I haven't experienced the fuser error

Edit: Fixed missing negative

Totally off topic: How can you not love Linux/UNIX, especially when we have errors telling us fuser.

So are you able to restore files?

Probably should restart the VM to see if that changes anything with the read-only issue.

Yeah I'm still getting that fusermount error...

There was definitely something wrong with the VM's state. Whoami returned unknown uid. Had to forcibly reboot from within XO.

Danp

Was actually able to pull up a file listing from one of my backups. Here's what showed in the log -

Yes, it appears to work in those cases where I can actually get a file listing.

DustinB3403

I do have fusermount under

/usr/share/bash-completion/completions/fusermount

Danp

This is what I get

xoadmin@xo-5:~$ whereis fusermount
fusermount: /bin/fusermount /usr/share/man/man1/fusermount.1.gz

Guessing that you either don't have it properly installed or it isn't in a location where it can be found.

DustinB3403

@Danp Do you have SSHFS installed?

DustinB3403

One sec, Fuse not installed on debian by default... FML... repo added installing fuse.

Rebooting and then recompiling..

Danp

@DustinB3403 Thought you did that yesterday. Did you rebuild from scratch?

No I added the universal repo yesterday for something else that was needed.

Anyways, now trying to mount a single backup I get

Seems to be specific to that backup, as I am able to restore files to my file server now without issue.

So a few things to we should try to compile into the update script, check for fuse, and install it if its not there.

DustinB3403

Another is listing things like this....

398.675872] ntfs: (device loop0): ntfs_readdir(): Directory index record with vcn 0x0 is corrupt.  Corrupt inode 0xe96b9.  Run chkdsk.
398.675890] ntfs: (device loop0): ntfs_readdir(): Directory index record with vcn 0x0 is corrupt.  Corrupt inode 0xe96b9.  Run chkdsk.

So yeah.. gonna run a check disk on my VM here..
