I have a dedicated server I rent from Hetzner in Germany. It has an Xeon E5-1650 V2 processor (6 cores, 12 threads, 3.5Gz base, 3.9Gz turbo), 128Gb RAM, and a pretty impressive 15 6Tb HDD. All drives are hooked to a Mega RAID controller, but because I am running ProxMox, I left it in JBOD mode and set up the 15 drives in RAIDZ-2. All 15 drives are in a single pool (probably not ideal, but it works for me). Now and again, I get a message from ProxMox telling me about bad blocks… and every time it happens, I have to remember what to do to find the bad drive, report it to Hetzner, wait for them to replace the drive and then add it back to the pool… Today, it happened, so I thought I better document it, to help future me, and hopefully someone else out there…https://www.tiernanotoole.ie/2023/03/15/day-56-of-100daysofhomelab.htmlWed, 15 Mar 2023 22:57:54 +0000https://www.tiernanotoole.ie/2023/03/15/day-56-of-100daysofhomelab.htmlDay 56 of #100daysofhomelab and I managed to fix some stuff with my TrueNAS box. There was lots of messing when it came to permissions, but it works now. Some speeds are below. Not quite getting the speeds I was expecting, but there I have not tweaked anything, yet… This is going from my MacBook Pro with a 10Gb adapter. The reads are quite good, but the writes… well, the HDDs are FASTER than the NVMe… No idea why… I did get a new card to add another 4 NVMe drives in… We’ll see what happens when that gets built.https://www.tiernanotoole.ie/2023/03/07/zfs-over-multiple-dvd-bd-r-images.htmlTue, 07 Mar 2023 09:42:46 +0000https://www.tiernanotoole.ie/2023/03/07/zfs-over-multiple-dvd-bd-r-images.htmlA couple of days back, I started thinking about archiving and backup software. I kind of have backups “sorted”, with my MacBook Pro using BackBlaze to backup to the cloud, Time Machine backing it up to my Synology, my VMs on Proxmox being backed up to Proxmox Backup Server off-site, my Synology and QNAPs being backup to B2 and Hetzner and some other bits and bobs… But for the Archiving stuff, I am not really set up… So, I went looking for archiving software. Couldn’t find anything, so asked on r/DataHoarder. Still no options, at the time of posting, but someone did reply with the idea of using DVDs (or Blu Rays) for ZFS...https://www.tiernanotoole.ie/2023/02/07/day-36-of-100daysofhomelab.htmlTue, 07 Feb 2023 21:39:16 +0000https://www.tiernanotoole.ie/2023/02/07/day-36-of-100daysofhomelab.htmlDay 36 of #100daysofhomelab and after yesterday’s post about RAID 10 on my external array, I found ZFS on OSX, and well, now I have a ZFS RAIDZ pool setup. It is showing as around 28.8Tb usable space, and so far, so good. Other than that, I have been looking into Ubuntu Landscape to monitor my Ubuntu fleet of machines. If you host it in-house, you get 10 machines for free, so hopefully, that’s enough for me to start with. I am working on getting it running on 22.04, using these beta install steps. RB5009 install is still pending. keep hitting stupid blocks stopping me from doing it, but hopefully this week. https://www.tiernanotoole.ie/2023/01/15/day-12-of-100daysofhomelab.htmlSun, 15 Jan 2023 01:38:59 +0000https://www.tiernanotoole.ie/2023/01/15/day-12-of-100daysofhomelab.htmlDay 12 of #100daysofhomelab and I am still battling with my ZFS pool on my Plex Server… So, that has taken all my time today… ugh…https://www.tiernanotoole.ie/2023/01/13/day-11-of-100daysofhomelab.htmlFri, 13 Jan 2023 22:03:40 +0000https://www.tiernanotoole.ie/2023/01/13/day-11-of-100daysofhomelab.htmlDay 11 of #100daysofhomelab and i am trying to fix my Plex Server… Seems when i moved from Fedora to Ubuntu, my ZFS pool did not import. I did not notice this, since mostly what is on it was temp files and logs… Well, the main drive is running out of space, so I checked the ZFS and it was failing because the version of OpenZFS I was running on Fedora (from master in their GitHub repo) is not compatible with the one on Ubuntu… (facepalm) So, have to rebuild and install OpenZFS from code… hopefully this works… [Edit… it did not work… ugh] [Edit 2: This did work though: Installing ZFS on Ubuntu (uptrace.dev) especially the part of building from code].https://www.tiernanotoole.ie/2020/11/04/backups-backups-backups.htmlWed, 04 Nov 2020 10:38:58 +0000https://www.tiernanotoole.ie/2020/11/04/backups-backups-backups.htmlI have posted about backups a few times on this site in recent years, and its still something I make tweaks to every now and again. The latest setup is probably over the top, but I will give you a walk though on it and some of it could be useful to some of you. I have a couple of different machines and storage devices running that need backups. Some need daily backups, some could get away with weekly. The list is as follows:
