Performance issues This NFS Howto page has some useful information regarding performance. RethinkDB member danielmewes commented May 17, 2016 A work-around is to start your own RethinkDB server by the way and then using the --start-rethinkdb no -c localhost flags with --dev. From: Gerald [mailto:[EMAIL PROTECTED] Increase the timeout on your popper. Today I updated horizon to 1.0 and the client could not connect anymore to the server via websocket. Source

If they are not, start and enable them. On some systems detecting the domain from FQDN minus hostname does not seem to work reliably. Henceforth, nfs-utils uses NFSv4 per default instead of NFSv3. danielmewes added the bug label May 17, 2016 dalanmiller commented May 17, 2016 horizon 1.0.1 is now published to npm https://www.npmjs.com/packages/horizon andrewsomething commented May 17, 2016 Confirming that I can no https://bugs.debian.org/160494

MOUNTD_OPTS="--manage-gids" "Permission denied" when trying to write files as root If you need to mount shares as root, and have full r/w access from the client, add the no_root_squash option to This is assuming you've already gone into the Advanced tab on the configuration and set the timeout to 5 minutes. When you're writing lots of small files from the client, this means that the server spends most of its time waiting for small files to be written to its disk, which

If your buffer size is too big, the kernel or hardware may spend too much time splitting it into MTU-sized chunks. It doesn't matter if after a client has written a file, and the client thinks the file has been saved, and then the client crashes, the file may be lost.

With the timeout at 60 seconds that was the error msg it would record. It's not important to you that if the server crashes: You may loose the files that were most recently written by clients. Unfortunately we haven't written a beta migration guide so far.

Essentially, data is accumulated into buffers before being sent. Here are some further tips: Diagnose the problem Htop should be your first port of call.

(Discuss in Talk:NFS/Troubleshooting#) NFS shares have to reside in /srv - check your /etc/exports file and if Check This Out The size of the buffer will affect the way data is transmitted over the network.

If you're happy with the above conditions, you can use the nocto mount option, which will disable the close-to-open behaviour. LinkReply

To increase the number of threads on the server, edit the file /etc/conf.d/nfs-server.conf and set the value in the NFSD_OPTS variable.

The most obvious symptom will be a maxed-out CPU. Counts the number of times a given interval are busy * ra (read-ahead): <10%> <20%> ... <100%> - cache-size: always the double of number threads - 10%, 20% ... If files are still showing as nobody after the above changes, edit /etc/idmapd.conf, ensure that Domain is set to FQDN minus hostname. There appears to be nothing the POP server can do to help.
