An interesting NFS question looking for comments.
Setup is:
System A (sysA) shares two files systems, one a subdirectory (hierarchical)
of
the other:
share -F nf -o rw=sysB /fs1
share -F nf -o rw=sysB /fs1/fs2
System B (sysB) has autofs running and therefore can read and write files in
/net/sysA:/fs1 and /net/sysA:fs1/fs2.
Facts:
- Autofs will not allow hierarchical mounts in /etc/auto_direct. (Yes I know
its not a good thing, but I have no choice.)
- NFS mounts in /etc/vfstab will have issues if the share/mount is not there.
Things like long logins when telneting to sysB.
- A symbolic link on sysB to the higher directory on sysB will allow for
transverseing all shared levels. I.e. on sysB
ln -s /net/sysA/fs1 /fs1
- If the share is missing simple and non-locking messages are presented to
sysB (i.e. telnets still work quickly and "NFS stale handle" don't hang the
user).
Question:
Does using symbolic links as described provide a "better" solution for
mounting hierarchical shares or just just NFS mounting in general? Does
anyone see a true down side here?
