Hi all, I have just installed Debian Woody on a Ultra5 box: I spanned a Raid1 volume across two ide disks: hda6, hdc6 and I'm sure /etc/raidtab is correct (I use software raid from the beginning...) let me show you: raiddev /dev/md0 raid-level 1 persistent-superblock 1 nr-raid-disks 2 nr-spare-disks 0 chunk-size 4 device /dev/hda6 raid-disk 0 device /dev/hdc6 raid-disk 1 When I do mkraid I can see from /proc/mdstat that everything is going well. During the construction of the volume I can create a ext2 or ext3 filesystem on it, I can mount it and read, write files on it. AND... when the construction of the volume finishes I can't do ANYTHING on the volume. e.g. if I try to mount it I get: data_access_exception: SFSR[0000000000801009] SFAR[fffff80338e39efc], going. \|/ ____ \|/ "@'/ .. \`@" /_| \__/ |_\ \__U_/ mount(566): Dax I tested this with the 2.4.18 kernel which comes with the Debian distribution and with the 2.4.19 kernel which I have compiled: nothing changes. Surprise: the same thing does not happen with a raid0 volume. Suggestion?
