Hi dear,
I would like to add a zfs volume to a lx branded zone.
I tried two ways
1. mount device
2. mount file system
But both failed, so I turn to your help. Maybe there is bug here.
Firstly I use zonecfg to add device to this virtual machine, but when I restart
the user zone, I found nothing under device path /dev/zvol/rdsk/, which means
failed to add this device.
Therefore, I try another way, I attend to mount file system instead of device.
I run following commands, please kindly help me check,
set dir=/wvol
set special=/dev/zvol/rdsk/zones/wvol //the zfs volume in the global zone
set raw=/devices/pseudo/zfs@0\\:20\\,raw //this is the wvol link to the device
set type=lofs
after restart the user zone:
[root@bdb4c6af-a595-ebf4-84a2-b4b7b52bf6a8 ~]# ll /wvol
crw------- 1 root sys 0, 94371860 Jul 21 10:45 /wvol
[root@bdb4c6af-a595-ebf4-84a2-b4b7b52bf6a8 ~]# stat /wvol

I suspect the device type in red font above is incorrect, so I run stat command
on global zone as comparison.
[root@public-cloud-4 ~]# stat /devices/pseudo/zfs@0:20,raw
File: `/devices/pseudo/zfs@0:20,raw'
Size: 0 Blocks: 0 IO Block: 8192 character special file

I believe something wrong on lx branded zone, because the device type is an
invalid value 5a00014, to my experience, it seems to be an address access
error, the correct value should be 5a,14. So I report this issue to you.
How can I fix this issue and mount a volume correctly?
Regards
xin.
