So I'm looking to migrate to another obscure file system. JFS.
My favourite. Except for test systems with ext4, everything here is JFS. Has been since ... forever. JFS v1.1 maybe.
I've used JFS extensively for many years (hmm over a decade) on IBM AIX machines.
The Linux variant of JFS is based on the JFS that was re-developed/-written for OS/2.
My one question is about concurrency. In some ways it a dumb question. The Linux implementation of JFS was done by IBM engineers so presumably it reflects the way the IBM AIX implementation worked, but I can't find an explicit answer in the extensive AIX documentation I have either.
Is JFS multi-threaded?
What does that mean?
And please, this is a desktop, not a file server, so advantages such as dealing with 16Tb files or file systems are of little importance, but the handling of lots of smaller files (such as ReiserFS does very well) *IS* important. That is why I'm asking about multi-threading. That's the ReiserFS limitation for me.
Sounds to me like you just ought to try it out. You're not making a strategic decision for the future, you can always change to something else. JFS is a mature filesystem that just works and works and works. IIRC, Backblaze (storage provider) used to swear by JFS. -- Per Jessen, Zürich (3.4°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
