Subject: [linux-lvm] confused with lvm2 filter rules
Date: Mon, 3 Jun 2019 13:03:39 +0000 [thread overview]
Message-ID: <3cc84c6a-62d0-96c2-cf6e-9181577f9802@suse.com> (raw)
Hello,
I met below filter action when executed 'vgextend'.
why the filter take no effect on executing pvcreate or vgcreate?
```
# ls -l /dev/disk/by-id/scsi-*
lrwxrwxrwx 1 root root 9 Jun 3 20:44 /dev/disk/by-id/scsi-360073a707 ->
../../sda
lrwxrwxrwx 1 root root 9 Jun 3 20:44 /dev/disk/by-id/scsi-36007c0036 ->
../../sdb
lrwxrwxrwx 1 root root 9 Jun 3 20:27 /dev/disk/by-id/scsi-3600b99ec4 ->
../../sdc
# pvcreate /dev/disk/by-id/scsi-36073a707 /dev/disk/by-id/scsi-36007c0036
# pvs
PV VG Fmt Attr PSize PFree
/dev/sda lvm2 --- 2.00g 2.00g
/dev/sdb lvm2 --- 2.00g 2.00g
# vgcreate vgtst /dev/disk/by-id/scsi-36073a707
/dev/disk/by-id/scsi-36007c0036hy the filter take no effect on executing
pvcreate or vgcreate?
# vgs

# vgextend vgtst /dev/disk/by-id/scsi-3600b99ec4
Device /dev/disk/by-id/scsi-3600b99ec4 excluded by a filter.
# vgs
VG #PV #LV #SN Attr VSize VFree
vgtst 2 0 0 wz--n- 3.98g 3.98g
my enviroment:
# rpm -qa | grep lvm2
lvm2-clvm-2.02.180-8.16.x86_64
lvm2-cmirrord-2.02.180-8.16.x86_64
lvm2-2.02.180-8.16.x86_64
the filter rules: (you can see all the disk in /dev/disk/by-id/ are
rejected)
# grep filter /etc/lvm/lvm.conf | grep -v "#"
filter = [ "r|/dev/.*/by-path/.*|", "r|/dev/.*/by-id/.*|",
"r|/dev/fd.*|", "r|/dev/cdrom|", "a/.*/" ]
```
Thank you.
