Hello,
My system is a Sun Fire X 2100 with RHEL 4.0. It has two 80G ATA SCSI
disks. Right now, one of them is failing, and I need to remove it off
the LVM Group.
Here is the LVM layout:
# df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 151527604 15281032
128549372 11% /
/dev/sda1 101086 18896 76971 20% /boot
none 1036912 0 1036912 0% /dev/shm
But when I run vgdisplay, the system only have 160MB Free PE.
# vgdisplay
--- Volume group ---
VG Name VolGroup00
System ID
Format lvm2
Metadata Areas 2
Metadata Sequence No 3
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 2
Open LV 2
Max PV 0
Cur PV 2
Act PV 2
VG Size 148.91 GB
PE Size 32.00 MB
Total PE 4765
Alloc PE / Size 4760 / 148.75 GB
Free PE / Size 5 / 160.00 MB
VG UUID P7GrJk-v55z-YHlz-xPYL-v0eJ-jL6V-Cdo5OO
As the usage is only 11% for VolGroup00-LogVol00 as shown by "df -k", I
don't know why I only have 160MB PE free.
I tried "pvmove /dev/sdb1", got the error message "insufficient suitable
contiguous allocatable extents for logical volume pvmove 0:2384 more
required, unable to allocate temporary LV for pvmove".
Can someone please help me out?
Thanks a lot in advance,
Joann
