Can't that do snapshots like BtrFS, like ext4? No, or not currently. Actually, XFS shares some devs and features with btrfs.
I recall reading that XFS could do snapshots but required (a) not to mount via uuid and (b) a "freeze" option. I also recall that the freeze option became kernel sported and could even be used with ext3, but I don't recall where I read that.
3rd hand gossip -- they just implemented a non-default option to do store a checksum of metadata if you also used the new features to keep around a special extent for free space. the GUID, apparently, was also part of the "metadata" that was crc'd. (BTW, I had a cow when I heard this)...but a _patch_ was submitted within the last week to move the user-settable GUID out of the crc'd data...). But I still don't like being forced to have crc'd metadata just to get the free-space extents -- they said it was needed for reliability -- which may be true, dunno, it sounded like an "agenda-ist" excuse... i.e. something that doesn't make technical sense to *force* on users. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
