What should I do if the mount directory cannot be accessed?

1. Mount -l check the mounting situation of the directory, and cd in one by one. Record the problematic directory
2. umount -l /home/log/xxx # lazy uninstall
3. mount intranet ip:/var/log/xxx /home/log/xxx # remount

 

umount -f -l /fold
# -f forces umount, even if the nfs server still exists
# -l lazy umount, remove all references when the file system is not busy

 

The cluster log hits a machine tool: yum install nfs-utils, and you will have time to practice later
