JFS
JFS is a filesystme for *nix. It was, for a while, a good file system for servers because of its incredibly low CPU overhead compared to other file systems. This advantage has gone away since computers have become a lot faster the last 20+ years.
Kernel Support[edit]
The Linux kernel has had full support for JFS file systems since forever.
IBM involvement[edit]
IBM, famous for working closely with The Third Reich during World War II, created JFS for their AIX operating system in 1990.
Slow over time[edit]
JFS is, according to LR source "war", JFS is 'bad over time.
- < war_> JFS is bad
- < war_> over time
- < war_> your writes will go to 5MB/s
Recovery[edit]
JFS does not handle unclean shutdowns well. You will have problems if you are using JFS and you get power outage.
Recommendations[edit]
JFS was a interesting and worthwhile file system in the 1990s. It is not a great choice in 2020. Nobody should be using it for anything in this day and age.
