When the time comes to replace a drive, it is very nice to know which drives is missing. I created this drive map to help me figure out which drive disappeared. I created this drive-bay map using a combination of: zpool status sesutil map lsblk camcontrol /var/run/dmesg.boot I have not included /var/run/dmesg.boot here. If you […]

This post has been replaced by a new one. For reference, the previous post on this server is still available. FYI, this server is named after Joshua Slocum, who was the first person to sail single-handedly around the world. This server was upgraded on Feb 2 2019. Only the storage persisted. Everything else was upgraded.
I’m going to implement zfstools on all my ZFS-based hosts today. I first started using this tool in July 2019. In this post: FreeBSD 12.0 and 12.1 zfstools 0.3.6_1 sanoid-2.0.1_2 Local snapshots only I will be using zfstool only for creating local snapshots. If I wanted snapshots for sending to other hosts, I would probably

When I set up the R720 with internal SSDs, I used a SATA power splitter, a Y-shaped cable. Today I replaced it because of a known fire-hazard. I received an email from a reader urging me to replace it and supplied a reference to a known good cable. I happened to have that very cable.

This host has been retired. The services were distributed amongst r730-01 and r730-03. This host was often referred to as r720 or r720-01 (after r720-02 appeared on the scene) This replaces a previous post. I’ve been given a Dell PowerEdge 720. It contains: 6 x 400GB SAS SSDs – data01 zpool 2 x 100GB SAS
I recently migrated a bunch of jails from one server to another. Today I attached the Dell TL4000 tape library. A jail on this server copied Bacula backups from disk to tape. In this post: FreeBSD 12.0 Bacula 9.4.3 Dell R720 Investigation As anticipated, I needed to update the server configuration to cope with changed

I’ve been getting these messages in /var/log/messages on slocum for as long as I can remember. Today I found out why those errors are occurring. They are logged on the FreeBSD jail host for a Nagios instance I run. Nagios runs in a jail on that host. I’ve just been ignoring the messages, but today

I noticed this the other day, and thought it was interesting. When the jailed property is set on a ZFS fileset, it affects the mountpoint within the jail. If your jail uses allow.mount.zfs (known as allow_mount_zfs when using iocage), the mountpoints become relative to the jail. For example, in my poudriere jail, this is what

Well, this isn’t very nice.

In this post, I’m not exporting an iocage jail to another host. I am moving the entire iocage instance to another host. This is accomplished by doing a zfs export on the zpool, moving the drives to a new system, and doing a zfs import. The drive migration is covered in a previous post. In
