This post has been replaced by a newer post. This is the Dell R730 host known as r730-01. For reference, the previous post on this server is still available. This host has undergone major storage changes over the past few weeks. This post will reflect those changes This is my primary developer server in my basement. gpart zpool list zpool status zfs list dmesg sesutil show [16:57 r730-01 dvl ~] % sudo sesutil […]
After finally creating data04, it’s time to relocate some data. In this post: FreeBSD 14.3 The source The current zpool which is straining is data01: I plan to move data01/bacula/volumes over first, then data01/bacula/working. Let’s modify the source for better results on the move. What do we have now? [20:22 r730-01 dvl /jails/bacula-sd-03/usr/local/bacula/volumes] % zfs get compression,recordsize data01/bacula/volumes NAME PROPERTY VALUE SOURCE data01/bacula/volumes compression on inherited from data01 data01/bacula/volumes recordsize 1M local Let’s

It’s time. Time to create the 8x 4T raidz2 zpool. These are the devices: disks=”nda0 nda1 nda2 nda3 nda5 nda8 da12 da13″ In this post: FreeBSD 14.3 Check for existing partitions Using the list above: [18:15 r730-01 dvl ~] % gpart show | grep -E “nda0|nda1|nda2|nda3|nda5|nda8|da12|da13” => 40 7814037088 nda5 GPT (3.6T) => 34 7814037101 nda8 GPT (3.6T) Note I could not do this command because it fails at the first error: [18:05

It’s time. Time to create the 8x 4T raidz2 zpool. That doesn’t happen in this post, hopefully the next one. But first, I have to move some stuff around, to free up all the 4TB devices. The host has 4 devices (NVMe) and I moved in two more, 4TB SSDs.

I recently migrated the zroot on r730-01 to a new pair of devices. I did not then configure swap for the swap partitions I set up. I’m going to do that now. I’m hoping this post from 8 years ago helps. In this post: FreeBSD 14.3 The first few sections include what’s in the system, and detects and fixes a few issues. Look for The real work near the bottom of the page.

On Nov 28, I rebooted r730-01 after an update, and it didn’t come back. At all. I had inserted 2x 4TB SSDS a few days earlier. It seems they contained remnants of a zroot. The host was trying to boot from them. I couldn’t get the host to boot from the real zroot. It frustrated me. I gave up and went to sleep later. The next morning, I moved those two drives into

Today I wanted to test some stuff with the newly obtained SATADOM SSDs. I was surprised to find they still had data on them. dvl@r730-04:~ $ gpart show ada1 => 63 242255601 ada1 MBR (116G) 63 1985 – free – (993K) 2048 495616 1 linux-data [active] (242M) 497664 193816576 2 linux-data (92G) 194314240 47939584 3 linux-data (23G) 242253824 1840 – free – (920K) Well, one of them at least. Let’s have a snoop.

Finally, it’s time to put together a new zpool for r730-01 (the storage information at that URL is already out of date; once this new zpool is created, another post will replace it). In this post: FreeBSD 14.3 I just realized, that my previous post on the zpools for this host revealed there is already a zpool with 2x 4TB NVMe: data02: [20:17 r730-01 dvl ~] % zpool list data02 NAME SIZE ALLOC

Now that r730-01 is booting from SATADOM devices (which are directly attached to the M/B, thereby freeing up drives bays / PCIe slots for larger devices), I thought it wise to buy a second pair. For two reasons: The price of used devices was pretty good It’s good to have spares nearby In this post: FreeBSD 14.3 smartmontools-7.5 smartctl info Here is the SMART info.

This post documents the drive locations for zpools within r730-01. It will be replaced from time to time with a new post. To the left of a device is an indication of the drive physical location. Unused devices Unused drives/slots: Slots 12 & 13 each contain a 4TB SSD. Slots 14 and 15 are empty. Those drive cages are on the workbench and each hold a 2TB SSD. There are also NVMe devices
