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.
