[TYPO3-english] TYPO3 on a NFS filesystem

[Loek Hilgersom]

Hi Olivier and Nicola,

The OS is Redhat and I admit I don't know which NFS version (I can't access all 
systems myself). PHP is 5.3.14.

We've been using TYPO3 4.5 and 4.6. With 4.6 we experienced many problems with 
the locking files. Locking method 'simple' was terrible, 'flock' reasonable but 
still not 100%. I would have preferred to use the 'semaphore' method but that 
flooded the syslog with warnings.

We've actually downgraded to 4.5 and the situation is much better now, but I'm 
still not 100% confident that it's all safe now.

Your suggestion to avoid temp dirs on NFS is useful. I discuss with the hoster 
what we can achieve there.

Any suggestions what to with the temp_CACHED* files, since typo3conf will 
probably stay on NFS? AFAIK there is no cacheConfiguration in the caching 
framework for that, or is there? I'll also check if disabling configuration 
cache entirely would incur a big performance penalty.

Thanks so far!
Loek
