I need some help mirroring my rpool.
I have a 60gb ssd running the rpool alone and want to mirror it for redundancy so I bought a 120gb ssd that I found for a good price. 60gb drives aren't as easy to find at a good price anymore it seems.
I (a bit naively) thought after reading http://docs.oracle.com/cd/E19253-01/...dep/index.html that it would be as easy to mirror as a storage pool using just zpool attach pool drive1 drive2, but I found out it is not.
Code:
:~# zpool status rpool
pool: rpool
state: ONLINE
scan: scrub repaired 0 in 10m47s with 0 errors on Sun Apr 2 00:06:47 2017
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c3d0s0 ONLINE 0 0 0
errors: No known data errors
:~# zpool attach rpool c3d0 c7d0
Error: c7d0s0 is part of an EFI(GPT) labeled device.
A required boot partition (BIOS Boot) was not found.
cannot attach c7d0 to c3d0: All disk labeling/system requirements are not satisfied.
c3d0 being the existing drive and c7d0 the new drive.
Trying to google the answer and looking in these forums I found some information (ZFS mirroring and Create a boot disk mirror on Solaris 10 x86) on how to proceed but I just can not get it to work properly. I am probably doing something wrong with partitioning but need help figuring out what.
If I run format and remove the EFI partition, create a new solaris2 partition and run zpool attach, the drive returns to EFI labels. Should it do that or am I missing something there too?
Yes I have.
I have tried to follow it but zpool attach replies with EFI labeled device and disk labeling requirements not met.
See my first post for exact message.
It does not matter if I use just c3d0 c7d0 or c3d0s0 c7d0s0, I get the same error message.
Am I missing something here, shouldn't this be running against slice two (s2)?

Indeed.

So the basic answer here is this, If you are building your zpool with virtual storage (I.E. Luns provided from a SAN, or storage exported from the global zone into the zone) you would use the whole disk I.E. c1d0. If you are in the global zone you need to provide it with the correct slice (partition). In Solaris the default slice for an OS is slice 2. So therefore you need to create the rpool against slice 2.
Using # zpool attach rpool c3d0s0 c7d0s2 worked and the second disk got added to the rpool. How come the Oracle documentation only shows s0 and guides everywhere only use s0?
On to the next issue, installing grub.
Code:
# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c7d0s2
raw device must be a root slice (not s2)
Unable to gather device information for /dev/rdsk/c7d0s2
So I tried s0 instead, as it is being mentioned in the oracle documentation.
Code:
# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c7d0s0
cannot read stage1 file /boot/grub/stage1
Error opening /boot/grub/stage1
# ls -l /boot/grub/
total 3101
-rw-r--r-- 1 root bin 57 Oct 21 2011 default_video_modes.txt
-rw-r--r-- 1 root bin 5432 Nov 27 17:53 grub_cfg_net
-rw-r--r-- 1 root bin 1032704 Nov 27 17:53 grub2netx64.efi
-rw-r--r-- 1 root bin 243848 Nov 27 17:53 pxegrub2
-rw-r--r-- 1 root sys 153272 Nov 27 17:53 splash.jpg
So it seems that stage1 is nonexisting, but this is perhaps as it should be? I do not know how installgrub works.
Reading the installgrub manual #man installgrub it says that installgrub is deprecated and that bootadm install-bootloader is to be used instead. Reading the manual for bootadm did not make me much smarter so I tried running it but failed. Just in case I made a snapshot of my rpool before trying.
Hi
Please let me know how to increase the size of rpool in solaris 11 in ldom. I know how to map the new LUN to LDOM after that please let me know the procedure to increase the rpool and how to identify new disk in OBP level of ldom as I need to set the new/lun to be my new boot device. (5 Replies)
I have a 240GB disk as rpool. I have installed Solaris 11.3 to a partition which is 110GB. Now I have another 130GB which is unallocated.

Hi guys,
I have a Solaris 10 x86 server with 2 physical disks. It had a ZFS rpool on the first disk c0t0d0s0. The server stopped booting with some error like "Cannot find bootfile".

Hi All;
My server's root partition was encapsulated with VxVM, I try to convert it to ZFS. I successfully de-encapsulated root. Now I try to mirror 2 root disks using ZFS. But I receive following error:

I'd like to finish setting up this system and then move the secondary or primary disk to another system that is the exact same hardware.
I've done things like this in the past with ufs and disk suite mirroring just fine. But I have yet to do it with a zfs root pool mirror.
Are there any... (1 Reply)
