http over nfs
hey all,

would like to ask if anyone has ever had any bad experience in serving http over nfs? (document root on nfs)

why should i avoid this, if its not recommended?

if the answer is nfs locks, i can tell apache to create the locks on local fs.

are there any other caveats apart from that?

Thanks,
Marc

blank text?

---------- Post updated at 04:26 AM ---------- Previous update was at 04:17 AM ----------

so far, what ive found is this:

1. EnableMMAP and EnableSendfile should be disabled
--> both seems to be inclined towards performance boost. Is it worth the switch to NFS? how much performance would I be loosing with these two turned off? Would there be serious noticeable degradation on a high-activity site?

2. logfiles and lockfiles should be on a local file system
--> I have no issues with this

3. right nfs mount options

One objection - NFS blocks forever when it is down, instead of returning an error.
NFS goes down for five minutes and your whole system freezes.

In almost any environment this will not fly.
