Отмонтировать недоступную NFS-шару

mount.cifs поддерживает опцию -l (lazy unmount)

в mount.nfs к сожалению этого нет

Похоже до сих пор существует эта проблема. Использование automount помогало.

Кажись

umount -f -l /mnt/share

>mount.cifs поддерживает опцию -l (lazy unmount) в mount.nfs к сожалению этого нет

man umount.nfs

NAME umount.nfs, umount.nfs4 - unmount a Network File System

SYNOPSIS umount.nfs dir [-fvnrlh ]

DESCRIPTION umount.nfs and umount.nfs4 are a part of nfs(5) utilities package, which provides NFS client functionality.

umount.nfs4 and umount.nfs are meant to be used by the umount(8) command for unmounting NFS shares. This subcommand, however, can also be used as a standalone command with lim- ited functionality.

dir is the directory on which the file system is mounted.

OPTIONS -f Force unmount the file system in case of unreachable NFS system.

-v Be verbose.

-n Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip deleting an entry.

-r In case unmounting fails, try to mount read-only.

-l Lazy unmount. Detach the file system from the file system hierarchy now, and cleanup all references to the file system as soon as it is not busy anymore.

-h Print help message.

NOTE For further information please refer nfs(5) and umount(8) manual pages.

FILES /etc/fstab file system table

/etc/mtab table of mounted file systems
