Hi all! I am having some troubles with mounting a vg consisting of two PVs. After booting, the partition /dev/sdb5 does not pop up (but 1-3 does and 4th is a swap). If i issue partprobe -s it does show up though. partprobe shows: /dev/sda: msdos partitions 1 2 3 /dev/sdb: msdos partitions 1 2 <5> /dev/sdc: msdos partitions 1 3 2 I don't know what <> means but that is one of the PVs If i, after issuing partprobe, use pvscan it shows: PV /dev/sdc2 VG Dreamhack lvm2 [1,23 TiB / 0 free] PV /dev/sdb5 VG gardin lvm2 [465,52 GiB / 0 free] PV /dev/sdd VG gardin lvm2 [465,76 GiB / 704,00 MiB free] Total: 3 [2,14 TiB] / in use: 3 [2,14 TiB] / in no VG: 0 [0 ] vgscan: Reading all physical volumes. This may take a while... Found volume group "Dreamhack" using metadata type lvm2 Found volume group "gardin" using metadata type lvm2 But the problems appear when: vgchange -ay gardin device-mapper: reload ioctl failed: Invalid argument device-mapper: reload ioctl failed: Invalid argument 2 logical volume(s) in volume group "gardin" now active Where dmesg shows: [31936.135588] device-mapper: table: 254:1: linear: dm-linear: Device lookup failed [31936.135592] device-mapper: ioctl: error adding target to table [31936.150572] device-mapper: table: 254:2: linear: dm-linear: Device lookup failed [31936.150576] device-mapper: ioctl: error adding target to table [31940.024525] end_request: I/O error, dev fd0, sector 0 And trying to mount the vg: mount /dev/mapper/gardin-root /mnt/tmp mount: you must specify the filesystem type I have googled some but can't find much about this issue, does anyone have any ideas how i can obtain the data stored on the disk? Because i really need it.. I am running debian squeeze with a 2.6.30-2-686 kernel, the partitions were originally created under debian lenny (don't know the kernel version back then though) lvm version shows: LVM version: 2.02.54(1) (2009-10-26) Library version: 1.02.39 (2009-10-26) Driver version: 4.14.0 Thanks in regards //Johan _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
