Rhel6.6---执行命令df -h卡住不动

Posted 2021-10-25 gyoungbean

问题描述

nfs服务宕掉后，df -h卡住不动，使用xftp也无法打开文档路径

-bash-4.1# mount
/dev/mapper/vg_root-LogVol00 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
/dev/mapper/vg_data-LV11408 on /myinst type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sdc1 on /backup type ext4 (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
10.23.134.9:/myinst/nfsback on /nfsbackup type nfs (rw,vers=4,addr=10.23.134.9,clientaddr=10.23.111.140)

发现/nfsbackup目录已经不存在，且nfs进程已经停止。卸载设备后正常。

-bash-4.1# umount -l /nfsbackup
