A couple of years ago I had a problem where a program was streaming data to a file. Unfortunately, the OS cached the contents in RAM and only dealt with it occasionally. The problem was that this would cause periodic delays of a long time while the cache was dealt with. Write calls would have to wait until this task was completed. See the following for the original discussion:
I remember.
Anyone have a clue about this? Maybe there is a better way to do this now? We are using ext4. IIRC, we tried other file systems at the time, but this was a general feature of all file systems.
My mistake. While the OS is ext4, the disks with the stream files (there are two) are xfs. Both of these are as it was in 13.1 when it last functioned.
As Dave mentions, maybe you should also format those disks to have the latest updates to the filesystem available. Or, perhaps better, create a test system with leap 15.0 and newly formatted xfs disks. Then I would ask on the xfs thread. I don't remember if you did so when the original thread arose. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
