Hello, I am experiencing similar, but maybe not exactly the same problem. I just upgraded fron 8.10 to 9.04 and cannot access my fakeraid disks with dmraid. I tried following:
sudo dmraid -ay RAID set "isw_eagedjaiic_Volume0" already active ERROR: dos: reading /dev/mapper/isw_eagedjaiic_Volume0[No such device or address] sudo dmraid -s *** Group superset isw_eagedjaiic --> Active Subset name : isw_eagedjaiic_Volume0 size : 1953536512 stride : 128 type : raid5_la status : ok subsets: 0 devs : 3 spares : 0 This looks similar to your problems so I tried following: sudo dmraid -an ERROR: dos: reading /dev/mapper/isw_eagedjaiic_Volume0[No such file or directory] sudo dmraid -ay ERROR: device-mapper target type "raid45" is not in the kernel RAID set "isw_eagedjaiic_Volume0" was not activated This raid set was working fine couple of hours ago on 8.10... Now I am a little bit sad missing my data ... -- Kubuntu Jaunty 9.04 dmraid fails with Kernel 2.6.28 https://bugs.launchpad.net/bugs/356503 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
