i have zfs pool made from 2 luns ( equallogic volumes).
i would like to add a third lun to the zfs pool , how do i do that ? can i do it while the zfs pool online?
for example , the zfs pool wgsi1-1 is made from 2 equallogic luns wgsi1-1 and wgsi1-11 , i want to add a third one say wgsi-111
here is the output from " echo | format " and " zpool status -v "
but how do i create device for the volume, when i run "echo |format " from solaris server i do not see the device.
also how can i make sure that i do not have raidz nor mirroring?
something new pop up on the format command output, what is this,
It looks like the format entry for device 9) is the new disk. Rather than being placed at format position 17,
its at 9. Are you sure this isn't the disk you are looking for? :-)
You don't have any mirrored or raidz pools because the "mirror" or "raidz*" keywords would be included in
your zpool status output. These are non-redundant pools so I hope these devices are from an underlying
hardware RAID array and you are monitoring their health and have good backups.
If all the other devices are in use, you can use format-->this disk-->partition to verify that it is unused. If
it is in-use by ZFS, you'll see a message to that effect.
If you are still unsure, you can always use the -n option to check the configuration:
i ran the command with -n , output
would update 'wgsi1-1' to the following configuration:
i created 7 new luns from my equallogics each is 500GB , now disk # 9 has strange name, how do i change the name to something meaningful?
also what commands do i need to run to discover the other 6 luns i created on storage equallogic? i mean i want to see the luns as disk from format command.
I'm better on the ZFS side than the 3rd party storage side. I would expect the LUNs to be visible on the host after you
identify which host will have access to them. If they are not immediately visible in format, then you might try devfsadm.
I hope someone more knowledgeable will comment.
I don't know if this works with remote storage, but if the format-->disk name looks strange, then you can try selecting
the disk and using the type command to automatically configure the device.
See Example 11-1 more towards the bottom of the page, here:
thanks for the follow up; ok i ran the devfsadm -v and now the "echo |foramt " is showing the new 7 created luns. i want to name them to something meaningful like wgsi1-111 and so on. now from the equallogic gui i named the new 7 lun the following : wgsi1-111 , wgsi1-121, wgsi1-131 , .... wgsi1-171 , how do i know which one correspond to which here in format.
I don't understand why the new names wgsi1-111 , wgsi1-121, wgsi1-131 , .... wgsi1-171 for the new LUNs are not showing
up like the previous wgsi1-1...wgsi1-17 names that are visible in format now, even though the new LUNs are visible. I don't
know how to fix this from the Solaris side of things.
one of my friends told that i have to go to format command and go to label and label it ,
so the process would be as following:
1- remove the lun/volumes from equallogic gui
2- run devfsadm -C to clear the devices
3- create one volume
4- run devfsadm to discover the device
5- run format -> change to desired label, for example, wgsi1-111
6- run the zpool add zpool-name <device for new volume to add>
7- check space , it should be 2.5TB
8- repeat the steps for rest of zfs pool
my friend suggested to do one at the time , this way you do not mix them up.
does it make sense?
can i run the following command on the solaris 10 without harming zfs filesystems already online and serving data
iscsiadm add discovery-address <address>:3260
iscsiadm modify initiator-node -c 3
iscsi modify discovery -sendtargets enable
