These would be quite handy for client-facing ML apps. Would love it if they enable encryption on these volumes too.
increase the size of the volume and expand the file system to match, with no downtime
Are there Linux filesystems that can be safely expanded without unmounting the volume?
not a linux expert at all – but my understanding is ext3 (and thus 4 as well) can be resized without un-mounting first.
xfs_growfs supports online growth of XFS fileystems (although it doesn’t support shrinkage).
Like pyvpx said, ext3+4 supports online resize.
It also looks like Btrfs supports online resize.
Is there any Linux filesystem that can’t be safely expanded without unmounting the volume? :)
Indeed, there are a number - ext3, ext4 and XFS, along with btrfs and ZFS too.
