I was in a Sun training class once where the instructor was extoling the virtues of ZFS at length. When I pointed out a dynamic filesystem might play havoc with DBs such as Oracle which like to keep their own disk references he allowed as how one probably shouldn't use it for them. 😊 I never used ZFS for anything but that was mainly because I was used to other tools such as LVM or VxVM (Veritas Volume Manager) on both commercial UNIX and Linux variants. P.S. I hated Solstice Disk Suite but Solaris used to require that for the boot/root drive (even if one had VxVM). VxVM was really good at doing software RAID. -----Original Message----- From: Ale <[email protected]> On Behalf Of Ron via Ale Sent: Thursday, January 1, 2026 7:58 PM To: [email protected] Cc: Ron <[email protected]> Subject: Re: [ale] to lvm or not lvm is my dillema Narahari Lakshminarayana via Ale wrote on 2026-01-01 13:44: > Does it make sense to install LVM ? There have been some solid answers already, so I'll add the option to use ZFS - not for boot but for /home at least. > What does it get me ? ZFS has some really great features - snapshots, send / receive features for duplicating data to a backup machine that's way, way better than anything else I can think of: Only changed blocks get sent. Move a multi GB file to another folder? Then rsync sends a whole new copy. ZFS just updates the meta data. Add a few bytes to a multi GB file? ZFS just sends the changed blocks. ZFS can self-heal corrupt data if redundancy is enabled (like RAID 1): read a block, calculate its checksum, if mismatch read other copy of data, calculate checksum, if valid send to user and replace bad copy, if both copies bad - warn user. There are a *lot* of nifty features, it's at least worth investigating as an option. _______________________________________________ Ale mailing list <mailto:[email protected]> [email protected] <https://mail.ale.org/mailman/listinfo/ale> https://mail.ale.org/mailman/listinfo/ale See JOBS, ANNOUNCE and SCHOOLS lists at <http://mail.ale.org/mailman/listinfo> http://mail.ale.org/mailman/listinfo _______________________________________________ Ale mailing list [email protected] https://mail.ale.org/mailman/listinfo/ale See JOBS, ANNOUNCE and SCHOOLS lists at http://mail.ale.org/mailman/listinfo
