ScaleIO Software: Failed to create physical volumes on Linux ScaleIO devices

摘要: pvcreate command on scinixx devices failed, because /etc/lvm/lvm.conf has not been configured properly.

文章内容


症状



On Linux host, with SDC installed, "pvcreate /dev/scinia" failed with "Device /dev/scinia not found (or ignored by filtering)."
When you use the verbose mode "pvcreate -vvv /dev/scinia" to check the detailed messages, you will see additional message like "/dev/scinia: Skipping: unrecognised LVM device type 252";

原因

Per ScaileIO Deployment Guide, the Linux LVM has to be configured before using scsinixx devices in the Linux LVM; in this case, this step has been ignored/skipped.

解决方案

Edit /etc/lvm/lvm.conf per Deployment Guide:

1. Edit the /etc/lvm/lvm.conf file by adding the following line:
types = [ "scini", 16 ]
2. If only scini devices are to be used, you can add the following filter:
filter = [ "a|/dev/scini*|", "r/.*/" ]
3. Once configured, the lvmdiskscan command should yield results similar to the following:
/dev/scinia [ 96.00 GiB] LVM physical volume
/dev/scinib [ 320.00 GiB] LVM physical volume
/dev/scinic1 [ 56.00 GiB]
/dev/scinid [ 32.00 GiB]
1 disk
1 partition
2 LVM physical volume whole disks
0 LVM physical volumes
4. Continue with normal LVM steps.
