A simple issue, but can be tricky nevertheless ! bareos-sd JobId 265: Warning: stored/mount.cc:270 Open device “FileStorage3” (/storage/block1) Volume “Full-0015” failed: ERR=stored/dev.cc:731 Could not open: /storage/block1/Full-0015, ERR=No such file or directory While experimenting I had made the owner of /storage/block1 different from the Bareos user; This resulted in the storage deamon (bareos-sd) not able to […]

Surprisingly perhaps for newbies such as myself; Bareos will only start one backup job at once; meaning if you got 100 clients, there will be a serieus delay between the first and last job. So why is this happening ? Bareos is a fork off Bacula and this was originally developed for the use of […]
Bareos uses FileSets to decide what to backup and what not to backup. While the documentation is extensive, the approach is mostly include everything and exclude parts (include all, exclude after). While this is the way average people want to backup. If you work around non-IT minded people, you know that they will store EVERYTHING, […]
By default the device used by Bareos for data archival/storage is FileStorage. Meaning data stored is stored in images on spinning disks in the file structure: /var/lib/bareos/storage While this might be a good place for you, its tricky with this location is in root … (full root and whatnot) You can change this in : […]
When installing Bareos client on Centos 7, I could not start the service with the following “cryptical error” : [[email protected] ~]# systemctl restart bareos-fd A dependency job for bareos-fd.service failed. See ‘journalctl -xe’ for details. [[email protected] ~]# systemctl status bareos-fd ● bareos-fd.service – Bareos File Daemon service Loaded: loaded (/usr/lib/systemd/system/bareos-fd.service; enabled; vendor preset: disabled ) […]
This is a quick howto, I made a raidz2 pool on ZFS, its very similar to how to create a mirror. find out what disks you are giving to the pool : [email protected]:~# fdisk -l /dev/sd* | grep Disk Disk /dev/sda: 9.1 TiB, 10000831348736 bytes, 19532873728 sectors Disk /dev/sdb: 9.1 TiB, 10000831348736 bytes, 19532873728 sectors […]
CellProfiler is not an easy to install tool; or perhaps I was clumsy on the first attempt (building from source) but I could not get it to work properly on a Linux machine; After another attempt using miniconda, I managed to get it running. This is just a documentation of how I got it working. […]
So I was happily using sanoid, when someone made me aware of pyznap (thanks !). Ever since that comment, it was on my to-do list to check out pyznap, but if a system works, why change it ? Definitely a important cog such as automated snapshots. The new version of sanoid, breaks comparability with older versions […]

Ever wondered what kind of checksum ZFS uses to check for bit rot ? Probably not, but it turns out you can change the used algorithm. However like most settings, the defaults are chosen by smart people. So changing it might not be doing you any favors. As it turns out, the default checksum used […]
