I've a LVM one physical volume "vg0" that created on 9 RAID devices. It worked still the day. But one day, I have problem about vgscan reports that it can't find my VG. And recovery data /etc/lvmconf/vg0.conf was broken by other cause. Please help me..... or give me hints to recover it. My VG structure is following /dev/md2,md3,md4,md5,md6,md7,md8,md9,md10 => vg0 Kernel Linux 2.4.5 #10 SMP The pvscan report is following >pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/md2" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md3" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md4" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md5" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md6" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md7" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md8" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md9" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/md10" of VG "vg1" [4.48 GB / 4.48 GB free] pvscan -- total: 9 [68.48 GB] / in use: 9 [68.48 GB] / in no VG: 0 [0] The pvdata report is following >pvdata -U /dev/md2 000: w1ozGmggQJ7LqDumRFhBWpxAcBuinvkV 001: gyivka8v8Rs8N6UHW1mXO2A7pe3V2UtL 002: N1rBqi3J4SXDpRwYCh65eXCtH98zrkYQ 003: vy3JnFfm4b4j5t1kcnnmPBVnqvKE1454 004: 3qwEJ6e08fnjyfEtYh2VUwNLSlAv7WHC 005: bCf2F3RgkdCqz0qs605zpQiMDF738U7Q 006: Ao8MnMZSLrDhk1pbTHatNA5KHiZXv5vG 007: 3ztQ2cfoGMc15y1TTXQzSpSkTIBzLcas 008: 9VW0My6FYEh4T1WnwBP3m0OSlMhdM7Gq 009: BIxTWheupMeCfEjU8UuyW0LX8gAq4aoD >pvdata -PP pvdata -PP /dev/md2 --- Physical volume --- PV Name /dev/md2 VG Name vg0 PV Size 8 GB / NOT usable 4 MB [LVM: 128 KB] PV# 2 PV Status available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 2047 Free PE 0 Allocated PE 2047 PV UUID gyivka-8v8R-s8N6-UHW1-mXO2-A7pe-3V2UtL pv_dev 0:9 pv_on_disk.base 0 pv_on_disk.size 1024 vg_on_disk.base 1024 vg_on_disk.size 4608 pv_uuidlist_on_disk.base 6144 pv_uuidlist_on_disk.size 32896 lv_on_disk.base 39424 lv_on_disk.size 84296 pe_on_disk.base 123904 pe_on_disk.size 4070400
