Hi, I already filed a bug about that [1] and now I hope somebody here can help me.
I have some servers, where I have to use the "hardware" raid controller PDC20277 (Promise Fasttrak). Under lenny it works fine using dmraid, but after the upgrade to squeeze (to be exact: after upgrading kernel and udev as mentioned in the upgrade guide [2]) the system doesn't boot anymore, because only one of the to identical ide disks gets configured and therefore the raid array is degraded and the system won't boot using the raid array. The reason for this seem to be new libata, which got introduced in 2.6.30 (I read that on "the internet" during my research) or the new pdc driver (pata_pdc2027x instead of pdc202xx_new). Or something else I don't see. Any ideas? The only idea I have so far is using an older kernel with debian squeeze. But then I wouldn't get security updates for it. I don't get why the system configures one of the two identical disks but not the other. It seems to "see" both disks: > scsi2 : pata_pdc2027x > scsi3 : pata_pdc2027x and then following a similar ata3 and ata4 line (ata2.jpg attached to bug report) [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=618798 [2] http://www.debian.org/releases/stable/i386/release-notes/ch-upgrading.en.html#upgrading-udev Thanks in advance Enno
