hi all,
I've been running LVM2 for a while and never had
any problems with it, so my knowledge is a bit limited because i've never had to
fiddle with it.
It started with me wanting to change my hda drive
cuz the old one was making alot of noice.
It's partitioning sheme is as
follows
/dev/hda1
[ 101.94
MB] /boot
/dev/hda2 [ 1.87 GB] / /dev/hda3 [ 23.00 GB] LVM physical volume /dev/hda4
[ 533.90 MB] SWAP
--- Physical volume ---
PV Name /dev/hda3 VG Name vgsys PV Size 23.00 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 4096 Total PE 5888 Free PE 0 Allocated PE 5888 PV UUID SegkSC-Thbb-DqRg-LSoA-tN0F-WmFp-K7CPCO --- Logical volume ---
LV Name /dev/vgsys/usr VG Name vgsys LV UUID cYrDRH-neMm-PwCZ-2Dlo-njJm-mBHs-NPZlu4 LV Write Access read/write LV Status available # open 1 LV Size 7.00 GB Current LE 1792 Segments 1 Allocation inherit Read ahead sectors 0 Block device 254:0 --- Logical volume --- LV Name /dev/vgsys/home VG Name vgsys LV UUID OX1Pkm-p6Vc-q6SB-9nxm-PRMl-TM1z-h5bcIc LV Write Access read/write LV Status available # open 1 LV Size 4.00 GB Current LE 1024 Segments 1 Allocation inherit Read ahead sectors 0 Block device 254:1 --- Logical volume --- LV Name /dev/vgsys/opt VG Name vgsys LV UUID GlQ5wV-ZzUu-51LW-okn6-82UV-9SFX-weiScV LV Write Access read/write LV Status available # open 1 LV Size 5.00 GB Current LE 1280 Segments 1 Allocation inherit Read ahead sectors 0 Block device 254:2 --- Logical volume --- LV Name /dev/vgsys/var VG Name vgsys LV UUID 1VvzOf-DLz1-GMp5-Xj24-r9Mp-yaOy-0t2yLw LV Write Access read/write LV Status available # open 1 LV Size 5.00 GB Current LE 1280 Segments 1 Allocation inherit Read ahead sectors 0 Block device 254:3 --- Logical volume --- LV Name /dev/vgsys/tmp VG Name vgsys LV UUID BAIl2N-5gVg-RzUZ-3IqL-L0D5-JiAk-bO2smA LV Write Access read/write LV Status available # open 1 LV Size 2.00 GB Current LE 512 Segments 1 Allocation inherit Read ahead sectors 0 Block device 254:4 Then i added a new 80GB drive at hdc and
run
dd if=/dev/hda of=/dev/hdc
then halt -h
changed disks and booted with the new 80GB disk
as hda...
now the strange thing...it cant find the logical
volumes at boot, so i end up with a very crippled system. if i list the lvm
volumes i see that they are there, but inactive at boot. i can reactivate them
and mount them manually...but then at reboot the same thing again.
what have happened?
I even tried to change back to the old drive, and
i was certain it would boot right up...but the exact same thing occured. GAAAH!
How can the source drive be altered? I don't get it.
Any ideas?
thanks!
/Fredrik
