-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am creating a recursive snapshot in my ZPOOL and I am getting an unexpected error:

"z-snapshotZFS" is a script doing a recursive ZFS snapshot of all my datasets and then deleting some of my snapshots like "dump" or "swap", email spool, etc. Any idea?. I have almost 60GB free in my pool... Even with the huge ZPOOL write reservation, I have: """ [root@stargate-host /]# zfs list datos NAME USED AVAIL REFER MOUNTPOINT datos 661G 16.6G 170M /datos """ 16.6GB free. Or is the 32GB reservation in "datos/swap" dataset hurting me here?. (BTW, wasting 50GB on the disk, or 7% of it is not nice. I know that that is for performance, but still...). If that is the case, how could I delete the 18GB references in "datos/swap"?. I am using only a bit of swap at this moment... """ [root@stargate-host /]# swap -s total: 1778312k bytes allocated + 261088k reserved = 2039400k used, 33412568k available """ 2GB, not 18GB... Should Solaris "trim" the swap space after boot/when it is swapped in?. I am using Solaris 10 Update 9. Thanks for your time. PS: Alternatively, could I do a recursive snapshotting of all my datasets skipping over a few of them?. Now I do a full recursive snapshot, and then delete specific snapshots I don't want to have, like the swap. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:j...@jabber.org _/_/ _/_/ _/_/_/_/_/ . _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTizuP5lgi5GaxT1NAQJEzQP9Ht9l8r+z2LeFOXI23m5RdCn+lnWnL9sD 4DPOr7fIn8noJ5/YW7+uusFKaOi51BzQMEtvgNDNN30SCEOZo5ZaSjU2EKJnxvdd 09lUlv1VUbFe9mmZPaLutEx4CNwbBjJBcyeviUbTlqJQWpjli4zASxDKjcnkuUY+ 9HLwujW2iCc= =8dDa -----END PGP SIGNATURE----- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
