Making sure I remove the correct drive

Leave a Comment / DELL, Disks, File Systems, hardware, R730 / By /

Yesterday, I discovered I had removed the wrong drive from a zpool. In this post: FreeBSD 14.2 Today, the zpool replace command has completed. Next, I carefully chose the right drive to pull from the drive bays. Status This is the zpool status, just before it completed: After it completed: I see gpt/SG_ZHZ16KEX is no longer in the zpool. Not trusting myself, I checked this way: [20:33 r730-03 dvl ~] % zpool status […]

FYI: This server has since gone to a new home. After powering off the server about 8 months ago, I took the first steps to selling it. I opened it up and took out 2x NVMe sticks (1TB each, ZFS mirrored, giving a 930G zpool) INTEL fiber NIC (Intel X540-AT2) I’ll be keeping those items. I also took an inventory of the drives still in the system: 10 x 5TB drives – all

Here I am, sitting on a beach, writing a blog post, and sipping a cool adult beverage. Reading email. I see this: I quickly ssh into the host to check zpool status: Lines 15-17 are relevant. There was a resilver event, which completed at 08:49:48 The vdev state changed event occurred at 08:49:34 That all seems to tie in, time-wise. More info than you want This displays vdev guids: Line 11 shows the

Replacing both drives in a zpool mirror

Leave a Comment / Disk Cloning, Disks, hardware, ZFS / By /

As previously mentioned, zuul has new drives. It is now time to replace the existing drives with the new drives. I will do this one at a time. Replace. Wait for resilver. At no time will the mirror be degraded (as would be the case if we removed a drive and mirrored). In this approach, we will mirror one of the drives to a new drive, and zfs will automatically remove the old

Adding a zroot pool to an existing system

Leave a Comment / beadm, Disks, File Systems, FreeBSD, hardware, HBA, ZFS / By /

Current FreeBSD versions will allow you to create a zroot zpool from which you can boot. However, when I created the main zpool for slocum (on Fri May 3 2:16 2013), that option did not exist. You might ask: how do I know that date? [dan@slocum:~] $ zfs get creation system NAME PROPERTY VALUE SOURCE system creation Fri May 3 2:16 2013 – At present, the system boots from a raidz2 zpool.

This post has been replaced by a newer post. This is the previous post for this system configuration. For future reference, this is the knew server … oh wait, I think it’s this server which is was mounted in the 3U chassis mentioned in this post (perviously erroneously referred to as a 4U). It runs a few jails, including Bacula regression testing services. It is now mounted in a SuperChassis 846E16-R1200B This recent
