I tried running
cat big.file >/dev/null
on bragi, where big.file is stored on the NFS-mounted JFS partition. For a
1.2GB file, it worked fine (and at about the speed I'd expect for gigabit
ethernet). For a 2.7GB file, it crashed but from the time it took, I'd guess
that it crashed before it had copied 1GB. Probably just chance then, and it
might've crashed when copying the 1.2GB file.
One other thing: I have another machine (loki) which has the same mount
options for its NFS shares but doesn't net-boot and I have used this to copy
multi-gigabyte files without any trouble.
To test things, I decided to mount the JFS partition on loki using the same
mount options as bragi does. True to form, it crashed the server so I'm
pretty sure the problem is to do with exporting JFS over NFS.
- Is it possible to set up a mythtv-friendly filesystem which is exportable
over NFS in a stable way? How does one do this? (If you're thinking XFS, I've
tried that one too and it's worse than JFS).
- Alternatively, is it possible to use ext3 with mythtv? what formatting
options do I use? What are the disadvantages?
