-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Andrew: ~ I have a quick question. Is software raid using mirror on two SATA drives more reliable that just using a single SATA drive if properly supported in the rc scripts? ~ My impression is that it's definitely better. The push back I'm getting here is that our box after power outages is hanging during boot and making the systems more unreliable. My feeling is that we just need to modify the rc files to correctly handle the situation and that the Linux From Scratch base may not have handled it and we might be better off taking a recent Linux system like Fedora 8 and check out it's config files in a mirror raid configuration. I suspect it's a easy fixed. Our new box will have dual power supplies, ECC memory, and either one or two hot pluggable SATA drives. My feeling is that this is an fantastic opportunity to use raid. One of our other products already uses raid with SCSI drives. I've see one problem where the raid got out of sync during a power outage but it was trivial to get the raid back in sync and think rc scripts could be easily set up to do this. Looks like a slam dunk to me to spend an extra $100 for a second drive and save our having to RMA the box in the event of a drive starting to fail. This afternoon I offered to make a $10k bet that it is as well as doing a lab test with a pair of systems being powered up and down every few minutes to verify my intuition. I got the ok to get your opinion on the efficacy of mirror raid for a network appliance running 2.6.16. Looks like kgdb is still on track for 2.6.25, hope Jason gets in back into your next mm patch and it goes mainstream. - -piet -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHv0N0JICwm/rv3hoRAukIAKCIvhgsJp1KAWGNRFkHczNsk9ibUQCfd0Ku kL9dqBpm6vUb1A1WZIW2544= =bbNu -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
