Here’s another quick one – although I have simply been lucky to find the answer so fast.
While having some documents going through corporate review, it was noted that the PDF and print versions wouldn’t show some parts using the expected fonts. Looking at the list of available fonts in Linux (via “fc-cat |grep NameOfMissingFont”), the font files were clearly included. But when checking the list of available fonts in LibreOffice writer, the fonts were nowhere to be found. Hence, although the template file for these documents referenced the correct fonts, LibreOffice substituted them “silently” by some other available fonts. Continue reading
Recently, we received reports of SCST-related error messages from one of our SAN servers:
kernel: [1082754.895993] : dev_vdisk: ***ERROR***: write() returned -28 from 4096
A quick analysis showed that these errors started on a working day right after holiday season, but during the evening hours (so no-one was actively working on-site). From then on, we saw roughly 10 to 30 similar messages per incident, with these incidents occurring 45 to 90 minutes apart. What caught our eye was the fact that these incident were always on a quarter-of-an-hour mark. Continue reading
Now that openSUSE Leap has been around for some time, I wanted to give it a try on one of our test SAN/NAS servers. One of the most basic elements of these SAN/NAS servers is using bcache to employ transparent block-level caching to SSDs, without the need for specialized RAID adapters. This allows for less expensive HDDs and/or more clients using these machines.
The current servers are running openSUSE 13.1, and using bcache right from the start (i.e. to put the root file system on a bcache device) was not for the faint of heart. So how have things evolved with Leap 42.1? Continue reading
