Hi, this is lustre 1.6.0.1 on redhat 4 update 4. With debian etch patchless clients and debian kernels 2.6.18. All are AMD64 bit. We use 1 MGS, 1 MDT and 5 OSS with together 10 OST.
The cluster is running since roughly 6 monthes, no problems on the server side up to know! The only problem on client side was, that two clients lost connection to mdt or ost and after recovering some files can't be accessed on this clients. After reboot of this clients everything was o.k.! But now we have a much more serious problem! It seems that it exists since a couple of days, but we just have found out what the reason is! A directory of one user with a couple of directories becomes temporarily unavailable on some clients. After a while one can access the directory again, but for me its not clear what happens and it vanishes also after a while. Reboot of the client does not change the situation. Now I have to ask for help, unfortunately its a production system and its needed as soon as possible. An update is planned, but most likely not realistic bevor middle of next month. What should I do next to solve or investigate the problem?
