Convert from XFS to EXT4

Support
1

Nethserver 7.3 installed by default with XFS. The filesystem has been giving me error on Proxmox (QEMU) snapshots.

  1. Is there a way to convert the filesystem to EXT4?
  2. If not, is there a clean way to move all my data to a new install. (I use SOGo)?

Thanks,
Gerald

Hi Gerald, why do you think ext4 is better ?

I don’t think he claims ext4 is better than xfs, but [quote=“gbr, post:1, topic:8625”]

SOGo mailboxes can be backed up through imapsync. I am in the progress of moving from SOGo to webtop. You can get some info here: Migrate SOGo to Webtop5

Not sure yet about calanders and addressbooks. Maybe through the PST route? Don’t know if you have windows clients running Outlook?

There are tools like fstransform but I didn’t test them. Be sure to have a working backup before trying filesystem conversion. The device to convert must be unmountable so you have to boot ie from a live iso to convert your NethServer root filesystem.

The backup/restore process may be an option but I didn’t test it in combination with a filesystem change. Just install the new machine with ext4 and restore the backup.

Another way would be imapsync as @robb suggested in combination with the new sogo backup:

Backup and restore procedures are not influenced at all by underlying F.S.
