| Post subject: | NFS fails |
G'day all, I have an issue where NFS fails after a while. I have some disks that I mount from another machine over NFS, they mount OK and are useable but after awhile the mounts hang when trying to access them. Any suggestions? |

I would start by looking at your log files and see if there are any clues there. Martian |

You could try using automount to control NFS mounts so they are only mounted when needed. https://wiki.archlinux.org/index.php/Autofs |

G'day all, Nothing in the logs. automount is an abomination  and should be avoided at all costs!
Would not help, since it fails during use. I solved the problem, brought a bigger disk and moved it locally so I no longer need to NFS mount. I think there must be an incompatibly between version somewhere since I have another box with nfs mounted disks and that does exibit the same problem. That box is a lot older. |

That first statement is not correct, but I suppose it depends on your definition of "the problem"

Yep that fixed it your car wont stall anymore. In terms that I deal with (SAF) that was a fix for the problem. |

Just thought that I would post that I have a similar issue sometimes while access my FreeNAS NFS mount. I only tend to get this freezing problem when I am doing a lot of copying to and from my NAS server. My Myth box is the only PC making an NFS connection to the NAS so I had always assumed it was a problem with the NAS. No real reason for that assumption, other than I didn't have any other problems with the Myth box. Though I also haven't had any other problems with the NAS. |

I'm having NFS connection failures using R6.03.00 Looking back through "messages.log" this entry is the first one about two hours after the last reboot. messages.log:Feb 13 20:03:37 Mythtv-LR nfs: server 192.168.1.15 not responding, still trying Can't find anything significant in any other logs except I notice a commercial flagging job started shortly before. mythtv/mythbackend.log:2011-02-13 20:03:28.280 JobQueue: Commercial Flagging Starting for CSI: Miami "Going Under" recorded from channel 65031 at Sun Feb 13 20:00:00 2011 In my previous R5F1 system the comflag jobs didn't start until after the recording finished. The recordings are on the local HD. the NFS mounts are only used for Videos & Music. Here's my fstab :- # <file system> <dir> <type> <options> <dump> <pass> none /dev/pts devpts defaults 0 0 none /dev/shm tmpfs defaults 0 0 /dev/sr0 /media/cdrom auto ro,user,noauto,unhide 0 0 UUID=33d197dd-a8ab-4d59-a3b0-55f1d05d6d38 / auto defaults,noatime 0 1 UUID=3ff11744-11fa-4dda-bd11-f6b7f1ca24e1 /myth auto defaults,noatime 0 1 UUID=405a5a3b-728f-426d-bc5f-b0ef2a817024 swap swap defaults 0 0 # mountpoints on ReadyNAS 192.168.1.15:/Media/mythtv/video /myth/video nfs nfsvers=3,tcp,noatime,intr 192.168.1.15:/Media/mythtv/music /myth/music nfs nfsvers=3,tcp,noatime,intr #STARTSCRUB --------------anything in this block will be scrubbed #ENDSCRUB Could the comflag job be the problem, or is there somthing wrong with my NFS mount statements ? The NFS is a ReadyNAS NV+ with plenty of space. Pete |

After a bit more searching on ReadyNAS forums I have changed the NFS server config to "async" mode, and increased the NFS threads from 1 to 4. So far seems to keep the connection up, but will see over the next day or so. UPDATE - still getting NFS failures. Not sure if it's the Myth box or the ReadyNAS. Pete |
