But, honestly, my users are only *extending* their space desires... BTW my operating system too :-) So, I never had the need to shrink a filesystem.

I can also claim lots of positive experiences with this, though mostly on 4.X systems (I've only recnetly started to use 5.X systems on more than a test machine). In my case, I growfs mirrored volumes. I've also deleted unused volumes (mirrored), moved their subdisks over to another volume to increase available free space and then run growfs to take advantage of the new space. It's been problem free for me, and I found myself taking advantage of volume management to solve disk management issues (like user home directories). -T -- "Robert Metcalf [the inventor of Ethernet] says that if something comes along to replace Ethernet, it will be called ``Ethernet'', so therefore Ethernet will never die.

That's encouraging to hear! Can you shrink volumes and filesystems like you can on, say, AdvFS under Tru64? That would be really nice.

Yes, it is. I use (g)vinum primarily as a LVM with concat plexes on ProLiant Servers with SmartRAID-Controllers, so mirroring and/or RAID5 is done in hardware. The extension of filesystems on concat plexes works (simply) as advertised... :-) At least *I* had no problems so far. -- Ciao/BSD - Matthias Matthias Schuendehuette , Berlin (Germany) PGP-Key at and ID: 0xDDFB0A5F ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I my case I had a legacy root-on-vinum all-mirrored setup, and so was interested in mirroring more than LVM. (Like many, I'd used vinum just as a way of accomplishing a software RAID 1 across two drives to provide extra tolerance to drive failures.) So, migrating from geom_vinum to geom_mirror was not such a burden (or a hurdle). I don't know if growfs is 100% robust enough yet to provide the other important ingredient to a true LVM storage management system a la the logical volume manager on AIX or AdvFS on Tru64, say.

Your observation is correct: it doesn't (yet) load balance across plexes of mirrored volumes; geom_mirror (gmirror) does, though (and offers various load-balancing options).

gvinum again?
I'm looking at gstat while fsck'ing a gvinum partition. The trouble I'm seeing is that I don't see activity on the second disk. Now... I'm using fsck -n ... just checking things ... so there's no writes, but does gvinum not (yet) load balance on reads? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
