[zfs-discuss] A possible interim alternative to ZFS boot
The following occurred to me as I''m in the process of debugging a SCSI boot problem (immediate reboot after I tell GRUB to "go" on a Tyan S2865 with a LSI Logic LSI20160B-F; every other possible use of the LSI board works.): While for the sake of simplicity and robustness we''d *like* everything to be under ZFS (insert some version of "This Ring, no other, is made by the elves...." :-), especially given the current pre-alpha state of ZFS boot and the various problems we''ve been hearing about, we don''t *require* booting off of a ZFS filesystem. Those of us who don''t want to be part of the "debug ZFS boot" effort could very possibly get along for now by having a minimal toe hold in, say, a SVM RAID-1 UFS / filesystem, and after that gets started, mount as ZFS filesystems the more dynamic parts of what are usually in a root partition, like /var. What do those of you who are familiar with the boot process, upgrading, etc. think? - Harold

In my case, I have two Boot Environments under UFS, with all the userdata under ZFS. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea at argo.es http://www.argo.es/~jcea/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:jcea at 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 v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQCVAwUBRmRTvJlgi5GaxT1NAQJFbwQApVjB+JWJlHl9pXLyhiHd7dFvVDYRwreq VNv/aD9ccZ5KXGysqRrVGh0BSpYOELgvVVzu4ATvJnO9ve+WqSB/rvYGrkePBw3T gCv3ZCyggsOSiXthJCqlRF0FfifTR0ZBFyT2wJeEDlH3WZZrMsRrcb1hStS9MZbz eMOvZtlhtwg=uhgL -----END PGP SIGNATURE-----
