[zfs-discuss] root pool expansion
Right now I have a machine with a mirrored boot setup. The SAS drives are 43Gs and the root pool is getting full. I do a backup of the pool nightly, so I feel confident that I don't need to mirror the drive and can break the mirror and expand the pool with the detached drive. I understand how to do this on a normal pool, but is there any restrictions for doing this on the root pool? Are there any grub issues?

Best you could do in this instance is to create a new pool from the detached mirror. You may want to consider keepting the redundancy of the mirror config so that zfs can automatically repair any corruption it detects. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] root pool expansion
Hi Gary, If your root pool is getting full, you can replace the root pool disk with a larger disk. My recommendation is to attach the replacement disk, let the replacement disk resilver, install the boot blocks, and then detach the smaller disk. The system will see the expanded space automatically. A mirrored root pool configuration is a good suggestion too. You need to follow the steps in the ZFS troubleshooting wiki (as suggested) to label and partition the replacement disk. http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide Replacing/Relabeling the Root Pool Disk Thanks, Cindy On 07/28/10 07:32, Gary Gendel wrote: Right now I have a machine with a mirrored boot setup.
