If I try to mount it with write access it locks up the whole OS -- no errors. I filled up the fs and then tried to move files off it and the whole thing crashed with unlink errors (If I remember correctly, it was a while back). I've tried a few things. I can run fsck.reiserfs successfully with out error. I can mount it read only. The three pvs don't have any free extents left so I tried adding a fouth pv and growing the lv and filesytem by 1Gb in oder to see if it would mount then, but it still froze. I tried to use pvmove to move one or two extents off the th other pvs onto the new one, but I couldn't figure out the syntax on how to move just one or two extents. I don't even now if that would work. I'm guessing it's an lvm problem, though I suppose it could be reiserfs or md problem instead. Any help or suggestions you might have would be greatly appreciated. here is the setup: lvm2 2.6.9 kernel on Gentoo one drive is sata on nforce3 chipset (sda) one drive is ata on nforce3 chipset (hda3) two drives are ata on pci adapter aec62xx driver (hde, hdg) amd64 architecture # pvdisplay /dev/cdrom: open failed: Read-only file system --- Physical volume --- PV Name /dev/hdg VG Name myvg PV Size 27.96 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 4096 Total PE 7157 Free PE 0 Allocated PE 7157 PV UUID rob6sx-6VLN-YmJW-cWPL-5KDn-jyHj-a2oVVE --- Physical volume --- PV Name /dev/hde VG Name myvg PV Size 27.96 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 4096 Total PE 7157 Free PE 0 Allocated PE 7157 PV UUID DSym9d-2yAa-56Ly-4V4e-E2w2-6yYX-aSqrFW --- Physical volume --- PV Name /dev/sda VG Name myvg PV Size 74.53 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 4096 Total PE 19079 Free PE 0 Allocated PE 19079 PV UUID LRqQiF-stsg-FHCl-lgGW-uj4T-azY6-NocqXC --- Physical volume --- PV Name /dev/hda3 VG Name myvg PV Size 9.03 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 2311 Free PE 2055 Allocated PE 256 PV UUID e6SUVH-xlss-4f02-9XUD-j4m0-ed9K-xcemNP # vgdisplay /dev/cdrom: open failed: Read-only file system --- Volume group --- VG Name myvg System ID Format lvm2 Metadata Areas 4 Metadata Sequence No 6 VG Access read/write VG Status resizable MAX LV 255 Cur LV 1 Open LV 0 Max PV 255 Cur PV 4 Act PV 4 VG Size 139.47 GB PE Size 4.00 MB Total PE 35704 Alloc PE / Size 33649 / 131.44 GB Free PE / Size 2055 / 8.03 GB VG UUID VuX0hq-qs9d-XZP2-vdZ6-rlwQ-RWqY-JHmNpj # lvdisplay /dev/cdrom: open failed: Read-only file system --- Logical volume --- LV Name /dev/myvg/mylv VG Name myvg LV UUID 07oG4N-NRJo-YxxH-iDy4-b8ck-7jq1-6hWc5F LV Write Access read/write LV Status available # open 0 LV Size 131.44 GB Current LE 33649 Segments 4 Allocation next free (default) Read ahead sectors 0 Block device 254:0 # dmsetup info Name: myvg-mylv State: ACTIVE Tables present: LIVE Open count: 0 Event number: 0 Major, minor: 254, 0 Number of targets: 4 UUID: VuX0hqqs9dXZP2vdZ6rlwQRWqYJHmNpj07oG4NNRJoYxxHiDy4b8ck7jq16hWc5F # dmsetup table myvg-mylv: 0 58630144 linear 34:0 384 myvg-mylv: 58630144 58630144 linear 33:0 384 myvg-mylv: 117260288 156295168 linear 8:0 384 myvg-mylv: 273555456 2097152 linear 3:3 384
