Hi again, I fixed my partition table problem and, now, it seems ok with my LVM volumes. But I can't mount them :-( # vgscan -ay device-mapper: reload ioctl failed: Invalid argument device-mapper: reload ioctl failed: Invalid argument device-mapper: reload ioctl failed: Invalid argument device-mapper: reload ioctl failed: Invalid argument device-mapper: reload ioctl failed: Invalid argument device-mapper: reload ioctl failed: Invalid argument 6 logical volume(s) in volume group "VG_Wilco" now active At the boot, I have other errors like : Internal error: PV segments corrupted in VG_Wilco PV segment pe_alloc... I've tried fsck but I can't... Do you know if I can recover my LV ? Here are some commands : # fdisk -l Disk /dev/sda: 400.0 GB, 400088457216 bytes 255 heads, 63 sectors/track, 48641 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x0009efa1 Device Boot Start End Blocks Id System /dev/sda1 * 1 30 240943+ 83 Linux /dev/sda2 31 48641 390467857+ 5 Extended /dev/sda5 31 48641 390467826 8e Linux LVM Disk /dev/sdb: 400.0 GB, 400088457216 bytes 255 heads, 63 sectors/track, 48641 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xace22e9e Device Boot Start End Blocks Id System /dev/sdb1 1 48641 390708801 5 Extended /dev/sdb5 1 48641 390708769+ 8e Linux LVM Disk /dev/sdc: 400.0 GB, 400088457216 bytes 255 heads, 63 sectors/track, 48641 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xcfcecfce Device Boot Start End Blocks Id System /dev/sdc1 1 48641 390708801 5 Extended /dev/sdc5 1 48641 390708769+ 8e Linux LVM Disk /dev/sdd: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System # pvscan -v PV /dev/sda5 VG VG_Wilco lvm2 [372.38 GB / 0 free] PV /dev/sdb5 VG VG_Wilco lvm2 [372.61 GB / 0 free] PV /dev/sdc5 VG VG_Wilco lvm2 [372.61 GB / 0 free] PV /dev/sdd VG VG_Wilco lvm2 [596.17 GB / 0 free] Total: 4 [1.67 TB] / in use: 4 [1.67 TB] / in no VG: 0 [0 ] # pvdisplay --- Physical volume --- PV Name /dev/sda5 VG Name VG_Wilco PV Size 372.38 GB / not usable 4.24 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 95328 Free PE 0 Allocated PE 95328 PV UUID dyVLCp-3kAD-wneq-VxVh-Nyr5-q6mn-wf6kjT --- Physical volume --- PV Name /dev/sdb5 VG Name VG_Wilco PV Size 372.61 GB / not usable 3.53 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 95387 Free PE 0 Allocated PE 95387 PV UUID ZEmHeZ-0DnH-VsvK-m9ju-7fdd-z2UH-5kTp4X --- Physical volume --- PV Name /dev/sdc5 VG Name VG_Wilco PV Size 372.61 GB / not usable 3.53 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 95387 Free PE 0 Allocated PE 95387 PV UUID kgMwfG-ugM6-dFeK-8358-EoZO-RuIJ-S0FqVv --- Physical volume --- PV Name /dev/sdd VG Name VG_Wilco PV Size 596.17 GB / not usable 344.00 KB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 152620 Free PE 0 Allocated PE 152620 PV UUID U3KSpz-6Yf6-QX03-erXL-AnPg-qxF9-1TTFXM # vgscan -v Reading all physical volumes.
