[linux-lvm] lvcreate error

[rich turner]

i have created a bunch of logical volumes on a single system with the
following commands:
#lvcreate -C n -l 512 -n backuplv -p rw --persistent y --major 253
--minor 255 -r 0 vg0
#lvcreate -C n -l 512 -n datalv -p rw --persistent y --major 253 --minor
254 -r 0 vg0
#lvcreate -C n -l 512 -n homelv -p rw --persistent y --major 253 --minor
253 -r 0 vg0
#lvcreate -C n -l 256 -n optlv -p rw --persistent y --major 253 --minor
252 -r 0 vg0
#lvcreate -C n -l 64 -n rootlv -p rw --persistent y --major 253 --minor
251 -r 0 vg0
#lvcreate -C n -l 128 -n swaplv -p rw --persistent y --major 253 --minor
250 -r 0 vg0
#lvcreate -C n -l 50 -n testllv1 -p rw --persistent y --major 253
--minor 249 -r 0 vg0
#lvcreate -C n -l 50 -n testllv2 -p rw --persistent y --major 253
--minor 248 -r 0 vg0
#lvcreate -C n -l 50 -n testllv3 -p rw --persistent y --major 253
--minor 247 -r 0 vg0
#lvcreate -C n -l 50 -n testllv4 -p rw --persistent y --major 253
--minor 246 -r 0 vg0
#lvcreate -C n -l 50 -n testllv5 -p rw --persistent y --major 253
--minor 245 -r 0 vg0
#lvcreate -C n -l 50 -n testllv6 -p rw --persistent y --major 253
--minor 244 -r 0 vg0
#lvcreate -C n -l 768 -n tmplv -p rw --persistent y --major 253 --minor
243 -r 0 vg0

when i try to create the next one it fails with the following error:
#lvcreate -C n -l 640 -n usrlv -p rw --persistent y --major 253 --minor
242 -r 0 vg0
Physical extent 0 of /dev/hdb2 referenced by more thatn one logical
volume. Couldn't fill extent allocation bitmaps vg0.

what did i do wrong?

Please report what version of LVM2 you're using ('lvm version') and
what architecture and what kernel.

If it's version 2.00.17 or later, please tar/zip /etc/lvm directory
and email it to me (not the list).  (Before that version, I'm not 
interested.)  Also enable debugging-to-log-file for the command that 
fails and send me the complete output (compressed).
  e.g. lvm.conf:  in log section:      
    file="/tmp/lvm2.log"
    level=7

Also (of course) try to reproduce with latest release (2.00.25).

[linux-lvm] lvcreate error

[ardy]

I'm trying to add a seventh logical volume on a two-disk, striped volume
group. vgdisplay shows the following:

--- Volume group ---
VG Name               vg0
VG Access             read/write
VG Status             available/resizable
VG #                  0
MAX LV                256
Cur LV                6
Open LV               6
MAX LV Size           255.99 GB
Max PV                256
Cur PV                2
Act PV                2
VG Size               14.24 GB
PE Size               4 MB
Total PE              3646
Alloc PE / Size       1436 / 5.61 GB
Free  PE / Size       2210 / 8.63 GB
VG UUID               v5Mf72-JidP-Fv7q-fm3G-TY95-21k9-4SV86i

I currently have six logical volumes mounted.
This is the rror I get when trying to create the seventh logical volume:

lvcreate -i2 -I4 -L4G -n lv6 vg0

lvcreate -- not enough allocatable/free physical volume space in "vg0"
lvcreate -- please check, if physical volumes are allocatable

I've redone this system, and the only difference is that I'm striping this
time. I was capable of creating more logical volumes when I wasn't
striping. Also, I could create a seventh volume using 3900MB, but not
4000MB.

Why is it choking at 4GB?

When you create a striped LV of 4g you will need 2g free on both disks. You can
check this with pvscan.
