проблема с NFS
Доброе всем утро!!
У меня возникла проблема с NFS (вернее она уже давно существует)
проблема такая
имеется 1 NFS сервер (DELL 6800 CPU Intel(R) Xeon(TM) MP CPU 3.16GHz x
8, Памяти 27 гигов)
к нему подключена полка с SCSI винтами U320 15k .. в RAID 5
смонтирован сюда этот диск
/dev/sdb1 807G 681G 86G 89% /storage
Монтируется так
/dev/sdb1 /storage ext4 defaults,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,noatime,nodiratime,noacl,errors=remount-ro 0 1
раздается через nfs так
/storage 192.168.15.0/24(rw,async,secure,no_root_squash,no_all_squash,no_subtree_check,fsid=root,no_acl)

Данная шара /storage раздается на 10 компов
Монтируется так
192.168.15.71:/ /storage nfs4 rw,rsize=65000,wsize=65000,proto=tcp,soft,intr,noatime,noauto,actimeo=240,acregmin=10,acdirmin=30,timeo=50,async 0 0
так вот в логах можно найти такое
2013/09/24 18:56:17 [crit] 10657#0: *847376 open() "summer-camp-block.jpg" failed (5: Input/output error), client: 95.108.158.234, server: blc.com.kg, request: "GET /sites/default/files/images/summer-camp-block.jpg HTTP/1.1", host: "www.blc.com.kg"
причем много.. потом это сообщение пропадает
и все вроде бы работает, но во время такой ошибки.. ессно файлы не
зачитываются
так это происходит ночью в основном (пред. ошибка была когда
сервер nfs был не доступен) так вот ночью с nfs сервера делается rsync
На другой сервер.. возможно из-за этого и выходит такая ошибка
так же есть такие ошибки
