Re: gmirror, gvinum or ccd to mirror root-filesystem under 6.0R
i plan to install 6.0-R in near future and ask myself if i should use gmirror, ccd or gvinum (again) for software-raid for mirroring the root file-system, as to: - reliability, stability issues - performance issues - minimum installation/configuration effort - advantages / disadvantages of gmirror vs. ccd vs. gvinum what are the experiences here ? Personally I currently do not trust vinum at all (any and all of my edge case tests / simulated hardware failures have turned into disasters). ccd I haven't tried, but I have set up root-on-gmirror on at three machines so far. I am very happy with gmirror; I have only observed two major problems so far. Firstly, geom/geom_mirror seems to obtain an exclusive open of the drive. this makes it a royal pain to update the boot sector of a drive while the system is booted with geom having claimed the device (and it doesnt help that boot0cfg does not report the error properly (and the patch i sent has been ignored so far)) Secondly, on at least one occation, the total failure of a mirror (rebuild test and the drive being rebuilt FROM had a bad sector) resulted in a kernel panic. The filesystem was mounted at the time, so I presume this isn't a problem with geom_mirror per se, but rather has to do with an attempt to access a destroyed geom or similar. (This wasn't the root filesystem btw - if it was the root filesystem then the system has a right to panic :)) -- / Peter Schuller, InfiDyne Technologies HB PGP userID: 0xE9758B7D or 'Peter Schuller [EMAIL PROTECTED]' Key retrieval: Send an E-Mail to [EMAIL PROTECTED] E-Mail: [EMAIL PROTECTED] Web: http://www.scode.org ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

However, for a simple root raid1, i find gmirror simple, straightforward, and pretty much error free. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
gmirror, gvinum or ccd to mirror root-filesystem under 6.0R
hi list currently i use gvinum under 5.4-R to mirror (raid-1) my root-file-system. works nice but was a little bit complicate/nasty to setup (basically it was the procedure as described on http://devel.reinikainen.net/docs/how-to/Vinum/#Chapter3.2 ) i plan to install 6.0-R in near future and ask myself if i should use gmirror, ccd or gvinum (again) for software-raid for mirroring the root file-system, as to: - reliability, stability issues - performance issues - minimum installation/configuration effort - advantages / disadvantages of gmirror vs. ccd vs. gvinum what are the experiences here ? thanks for answers, ~reinhard -- My mother drinks to forget she drinks. -- Crazy Jimmy ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
