Hello, so I had set up a rudimentary vinum configuration. I eventually rebooted the machine to make sure everything came up again correctly. It did, but it also picked up a couple of old drives and volumes that I had previously used for testing. "vinum l" now yields: 3 drives: D alpha State: up /dev/da0a A: 17244/488 MB (3532%) D backup_a_1 State: up /dev/ad1s1b A: 31/19531 MB (0%) D backup_a_2 State: up /dev/ad0s1a A: 39/19539 MB (0%) D beta State: referenced unknown A: 0/0 MB 3 volumes: V test State: up Plexes: 2 Size: 10 MB V test3 State: up Plexes: 1 Size: 20 MB V backup_a State: up Plexes: 2 Size: 19 GB 5 plexes: P test.p0 C State: up Subdisks: 1 Size: 10 MB P test.p1 C State: faulty Subdisks: 1 Size: 10 MB P test3.p0 C State: up Subdisks: 1 Size: 20 MB P backup_a.p0 C State: up Subdisks: 1 Size: 19 GB P backup_a.p1 C State: up Subdisks: 1 Size: 19 GB 5 subdisks: S test2.p0.s0 State: up D: alpha Size: 10 MB S test2.p1.s0 State: crashed D: beta Size: 10 MB S test3.p0.s0 State: up D: alpha Size: 20 MB S backup_a.p0.s0 State: up D: backup_a_1 Size: 19 GB S backup_a.p1.s0 State: up D: backup_a_2 Size: 19 GB The drives 'alpha' and 'beta', along with volumes 'test' and 'test3' are old remnants. The question now is - how do I correctly and safely purge them from my vinum configuration? I tried: scode-whitestar# vinum stop test scode-whitestar# vinum stop test3 scode-whitestar# vinum rm -r test Can't remove test: Device busy (16) As I interpret the manpage, the use of '-f' should not be required. And indeed, I assume that '-f' should never be needed unless in extreme cases? In any case. At the moment my vinum configuration *is* expendable since I have not stored any data on any of the volumes yet, however I want to know how to do this correctly so that I can do it on a live system in the future. Btw, after 'vinum stop', the volumes state show as 'down'. But after an attempted rm -r, they go back to state 'up' (both test and test3, even though I only try to remove test). -- / Peter Schuller, InfiDyne Technologies HB PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org
