Hi. I was using LVM1 for long time - about 3 years i think. yesterday i wanted to change to kernel 2.6.0 which has support for dev-mapper and LVM2 (at least I thaught so). I've downloaded newest stable lvm2-tools, and dev-mapper, compiled, and installed. all seems to work ok. but i have few questions, and 1 big problem. problem: when i try to extend my current old volume pvmove gives me an error: rn:~# pvmove /dev/hde1 device-mapper ioctl cmd 9 failed: Invalid argument Couldn't load device 'hyp-pvmove0'. ABORTING: Temporary mirror activation failed. device-mapper ioctl cmd 9 failed: Invalid argument Couldn't load device 'hyp-rn'. this is what i did: i have volume group: rn:~# vgdisplay --- Volume group --- VG Name hyp System ID rn1037982351 Format lvm2 Metadata Areas 9 Metadata Sequence No 30 VG Access read/write VG Status resizable MAX LV 2048 Cur LV 2 Open LV 0 Max PV 24 Cur PV 9 Act PV 9 VG Size 989.19 GB PE Size 16.00 MB Total PE 63308 Alloc PE / Size 53232 / 831.75 GB Free PE / Size 10076 / 157.44 GB VG UUID 46QFpN-LocC-JvQw-PDlc-5be6-x7pu-burVMz ive formated, and pvcreate /dev/hdk1 rn:~# pvdisplay /dev/hdk1 --- Physical volume --- PV Name /dev/hdk1 VG Name hyp PV Size 233.73 GB / not usable 0 Allocatable yes PE Size (KByte) 16384 Total PE 14959 Free PE 10076 Allocated PE 4883 PV UUID Yu16JP-A65t-pbC0-93FR-kI3B-3Jv4-duKJMT it shows that i have enough free space to move hde1 to hdk1. rn:~# pvdisplay /dev/hde1 --- Physical volume --- PV Name /dev/hde1 VG Name hyp PV Size 76.30 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 16384 Total PE 4883 Free PE 0 Allocated PE 4883 PV UUID GSRC0l-keb2-0BN2-Kgi5-8Hou-KVwE-ZtNPKS now I dont know what i do wrong. i always used to do this things with lvm1, but here is smth wrong. and my additional question is, why vgdisplay shows only MAX LV 256 when ive just turned to kernel 2.6.0 & dev-mapper & lvm2? it was supposed to be at least 1024, or 2048 (like it is now, coz ive edited some files - dont know if i did smth bad). how to fix my problem? i want to remove hde1 and hdg1. i got enough space on hdk. rn:~# pvs PV VG Fmt Attr PSize PFree /dev/hda2 hyp lvm2 a- 110.58G 0 /dev/hdb1 hyp lvm2 a- 114.47G 0 /dev/hdc1 hyp lvm2 a- 111.77G 0 /dev/hdd1 hyp lvm2 a- 114.47G 0 /dev/hde1 hyp lvm2 a- 76.30G 0 /dev/hdf1 hyp lvm2 a- 76.67G 0 /dev/hdg1 hyp lvm2 a- 74.53G 0 /dev/hdh1 hyp lvm2 a- 76.67G 0 /dev/hdk1 lvm2 -- 233.73G 233.73G and is there any good manual (like for veriosn lvm1, step-by-step configuring lvm2, and converting lvm1->lvm2?) and on dmesg i got this: device-mapper: error adding target to table device-mapper: device 254:001 too small for target device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table device-mapper: error adding target to table device-mapper: device 254:001 too small for target device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table I searched a lot on mailing list, but there is no solution for me. _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
