I have obtained a Dell R720 containing 10 x 400GB SSDs. The drives are connected to a RAID controller (H710P) which cannot do JBOD / IT mode. This means the drives are effectively hidden from ZFS, which is never good. In this post: FreeBSD 12.0 ZFS Dell R720 SAS 9207-8i This post describes past work and future plans for this server as I get it ready to be a general purpose server running […]

ZFS is very flexible about mountpoints, and there are many features available to provide great flexibility. When you create your second zpool this is what it might look like: $$ zfs list -r main_tank NAME USED AVAIL REFER MOUNTPOINT main_tank 893G 3.52T 96K /main_tank main_tank/data 786G 3.52T 88K /main_tank/data main_tank/data/dvl 755G 3.52T 755G /main_tank/data/dvl main_tank/data/freshports 31.4G 3.52T 88K /main_tank/data/freshports main_tank/data/freshports/backend 3.11G 3.52T 88K /main_tank/data/freshports/backend This is a pool I created long ago, but

This post has been replaced by a new one. For reference, the previous post on this server is still available. This server was upgraded on Feb 2 2019. Only the storage persisted. Everything else was upgraded.

This post has been replaced by a newer one. For reference, the previous post on this server is still available. The most recent change was extracting the beadm boot environment to a new zpool, zroot. For future reference, this is the slocum server, which I use for various jails and services. It is mounted in the 4U chassis mentioned in this post The filesystems, well, some of them: And dmesg:
I have added comments to the output of this command. This is a brief description of what runs in each jail.

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
For future reference, this is the knew server … oh wait, I think it’s this server which is mounted in the 4U chassis mentioned in this post.

I’ve been given a Dell PowerEdge 710. I’ve installed two 30GB SSDs, installed FreeBSD 11 on them, and added four 500 GB SSDs. It will become a tape library server, replacing the R610 which will no longer be used. Some of the hardware came from the R610. The zpools: The filesystems: And dmesg:
I recently installed 6 SSDs into an R710. In this post, I will describe what I did to the empty SSDs before I started using them. short test I ran a short test on each one of the drives.

I’ve been having boot issues with a server containing 20 HDD, all behind HBAs. I have decided to start booting off SSDs. In that previous blog post, there was much speculation about where to mount the new drives, etc. In the meantime, I came up with a solution which did not involve magnets and used a pair of INTEL 730 SSDs I had in another chassis. Let’s start with how I configured those
