Apart from being an aparent Linux user, I’m also a fan of FreeBSD. A few years ago I challenged myself to perform all work related tasks on a FreeBSD machine for 6 months. It turned out that FreeBSD’s been working out quite well as a general usage work desktop.

Right now, I’m preparing for my next exam - Red Hat Certified Specialist in Identity Management (EX362), and one of the topics is about setting up automated home directory using IdM (or IPA). I tried to follow the course material, but I had troubles getting it working. ...

ZFS is one of my favorite file systems. I use it at home on my nas server (running FreeBSD) as well as my Fedora 32 desktop. Today, I’m going to show you (and my future self) how to replace a (faulty) disk in a Zpool. The server I’ll be working on is nas2 and the pool is tank. List the status of the current pool. Password: root@nas2:~ # zpool status tank pool: tank state: DEGRADED status: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Attach the missing device and online it using 'zpool online'. see: http://illumos.org/msg/ZFS-8000-2Q scan: resilvered 472K in 0 days 00:00:02 with 0 errors on Sun Aug 23 16:17:21 2020 config: NAME STATE READ WRITE CKSUM tank DEGRADED 0 0 0 mirror-0 DEGRADED 0 0 0 diskid/DISK-Z4Z46MXG ONLINE 0 0 0 620907994788427922 UNAVAIL 0 0 0 was /dev/diskid/DISK-Z1E4ZCM2 mirror-1 ONLINE 0 0 0 diskid/DISK-Z1E5PFCH ONLINE 0 0 0 diskid/DISK-Z4Z46XQP ONLINE 0 0 0 errors: No known data errors From the above output, we can see that one of the disk in mirro-0 vdev was missing.
