Hello!
I've just created new pv & vg, wanted to create lv over it, but
suddenly found there is nothing in /dev or /sys/block or
/sys/class/block related to that vg
a bit info:
I already have another pvs & volume group (inktomia) & lv, working nice:
root@delta:~# vgscan
Reading all physical volumes. This may take a while...
Found volume group "vgsphinx" using metadata type lvm2
Found volume group "inktomia" using metadata type lvm2
new vg is "vgsphinx".
root@delta:~# vgdisplay vgsphinx
--- Volume group ---
VG Name vgsphinx
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 1
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 0
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size 111.79 GB
PE Size 4.00 MB
Total PE 28618
Alloc PE / Size 0 / 0
Free PE / Size 28618 / 111.79 GB
VG UUID 9TSHZX-DbFk-2kSl-RI6I-XYOH-gMho-eI2wsZ
filter looks ok too:
root@delta:~# egrep '^[[:space:]]+filter' /etc/lvm/lvm.conf
filter = [ "a/.*/" ]
nothing interesting in dmesg.
steps i did when trying to resolve issue:
root@delta:~# vgscan
Reading all physical volumes. This may take a while...
Found volume group "vgsphinx" using metadata type lvm2
Found volume group "inktomia" using metadata type lvm2
root@delta:~# vgchange -a y
0 logical volume(s) in volume group "vgsphinx" now active
1 logical volume(s) in volume group "inktomia" now active
root@delta:~# vgmknodes -v
Finding all logical volumes
root@delta:~# ls -la /sys/block/
total 0

so, /devices/virtual/block/dm-0 is from vg "inktomia", and there is no
new vg here

Yes, that was night blunting , and after send email button was pressed, i'v realized that until lv is created, there won't be any block devices, so no /dev/xxx entries ;) So problem resolved, everything is ok now, thanks! > > On Fri, Jan 28, 2011 at 4:20 AM, CoolCold <coolthecold@gmail.com> wrote: >> >> Hello! >> I've just created new pv & vg, wanted to create lv over it, but >> suddenly found there is nothing in /dev or /sys/block or >> /sys/class/block related to that vg >> >> a bit info: >> I already have another pvs & volume group (inktomia) & lv, working nice: >> root@delta:~# vgscan >> �Reading all physical volumes. �This may take a while... >> �Found volume group "vgsphinx" using metadata type lvm2 >> �Found volume group "inktomia" using metadata type lvm2 >> >> new vg is "vgsphinx". >> >> root@delta:~# vgdisplay vgsphinx >> �--- Volume group --- >> �VG Name � � � � � � � vgsphinx >> �System ID >> �Format � � � � � � � �lvm2 >> �Metadata Areas � � � �1 >> �Metadata Sequence No �1 >> �VG Access � � � � � � read/write >> �VG Status � � � � � � resizable >> �MAX LV � � � � � � � �0 >> �Cur LV � � � � � � � �0 >> �Open LV � � � � � � � 0 >> �Max PV � � � � � � � �0 >> �Cur PV � � � � � � � �1 >> �Act PV � � � � � � � �1 >> �VG Size � � � � � � � 111.79 GB >> �PE Size � � � � � � � 4.00 MB >> �Total PE � � � � � � �28618 >> �Alloc PE / Size � � � 0 / 0 >> �Free �PE / Size � � � 28618 / 111.79 GB >> �VG UUID � � � � � � � 9TSHZX-DbFk-2kSl-RI6I-XYOH-gMho-eI2wsZ >> >> filter looks ok too: >> root@delta:~# egrep '^[[:space:]]+filter' /etc/lvm/lvm.conf >> � �filter = [ "a/.*/" ] >> >> nothing interesting in dmesg. >> >> >> steps i did when trying to resolve issue: >> root@delta:~# vgscan >> �Reading all physical volumes. �This may take a while... >> �Found volume group "vgsphinx" using metadata type lvm2 >> �Found volume group "inktomia" using metadata type lvm2 >> root@delta:~# vgchange -a y >> �0 logical volume(s) in volume group "vgsphinx" now active >> �1 logical volume(s) in volume group "inktomia" now active >> root@delta:~# vgmknodes -v >> � �Finding all logical volumes >> >> root@delta:~# ls -la /sys/block/ >> total 0 >> drwxr-xr-x �2 root root 0 2011-01-27 23:34 . >> drwxr-xr-x 13 root root 0 2011-01-27 23:33 .. >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 dm-0 -> >> ../devices/virtual/block/dm-0 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop0 -> >> ../devices/virtual/block/loop0 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop1 -> >> ../devices/virtual/block/loop1 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop2 -> >> ../devices/virtual/block/loop2 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop3 -> >> ../devices/virtual/block/loop3 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop4 -> >> ../devices/virtual/block/loop4 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop5 -> >> ../devices/virtual/block/loop5 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop6 -> >> ../devices/virtual/block/loop6 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 loop7 -> >> ../devices/virtual/block/loop7 >> lrwxrwxrwx �1 root root 0 2011-01-27 23:33 md0 -> >> ../devices/virtual/block/md0 >> lrwxrwxrwx �1 root root 0 2011-01-27 23:33 md1 -> >> ../devices/virtual/block/md1 >> lrwxrwxrwx �1 root root 0 2011-01-27 23:33 md2 -> >> ../devices/virtual/block/md2 >> lrwxrwxrwx �1 root root 0 2011-01-27 23:33 md3 -> >> ../devices/virtual/block/md3 >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 sda -> >> ../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda >> lrwxrwxrwx �1 root root 0 2011-01-28 01:12 sdb -> >> ../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sdb >> lrwxrwxrwx �1 root root 0 2011-01-28 00:09 sdc -> >> ../devices/pci0000:00/0000:00:1f.2/host5/target5:0:0/5:0:0:0/block/sdc >> >> so, /devices/virtual/block/dm-0 is from vg "inktomia", and there is no >> new vg here >> >> system info: debian lenny with 2.6.32 kernel from backports: >> root@delta:~# dpkg -p lvm2|grep Version >> Version: 2.02.39-7 >> root@delta:~# cat /proc/version >> Linux version 2.6.32-bpo.5-amd64 (Debian 2.6.32-30~bpo50+1) >> (norbert@tretkowski.de) (gcc version 4.3.2 (Debian 4.3.2-1.1) ) #1 SMP >> Mon Jan 17 18:24:45 UTC 2011 >> >> >> I guess i'm missing something, please point me. >> >> P.S.
