cifs OSX -> debian jessie mount 中无匹配 glob 导致 io 错误

tag-icon • tag-icon bash mount cifs wildcard debian-jessie
cifs OSX -> debian jessie mount 中无匹配 glob 导致 io 错误

在 Debain Jessie 8.2 中，如果 samaba 挂载上没有匹配项，则使用通配符/glob（至少*和?）bash会导致出现错误。在其他文件系统上，会出现预期的错误。input/output errorcifsNo such file

相同的 samaba 挂载点位于 archlinux 机器上，没有 io 错误。Archlinux 机器mount.cifs可以理解mapposix。我怀疑mount.cifsjessie 上的“不允许/理解”mapposix与此有关。

有没有什么办法可以解决 io 错误*？

 ## works as expected on cifs mount from centos server
 ls /data/Luna1/*adfadf*
 # ls: cannot access /data/Luna1/*adfadf*: No such file or director


 ### unexpected io failure on osx mounted on debian
 mkdir /Volumes/Phillips/testdir

 ## no files match in empty directory: io error
 ls /Volumes/Phillips/testdir/*
 #  ls: reading directory /Volumes/Phillips/testdir/*: Input/output error

 ## glob matches, ls results
 touch /Volumes/Phillips/testdir/file
 ls /Volumes/Phillips/testdir/*
 #  /Volumes/Phillips/testdir/file

 ## glob matches, ls results
 ls /Volumes/Phillips/testdir/*il*
 # /Volumes/Phillips/testdir/file

 ## no files match: io error
 ls /Volumes/Phillips/testdir/*foobar*
 #  ls: reading directory /Volumes/Phillips/testdir/*foobar*: Input/output error

 # fails as expected
 ls /*filedoesnotexist*
 #  ls: cannot access /*filedoesnotexist*: No such file or directory

 ## zsh handles this correctly
 zsh -c "ls /Volumes/Phillips/*dne*"
 #  zsh:1: no matches found: /Volumes/Phillips/*dne*

我当前的解决方法是触摸与 glob 匹配的文件以避免错误

bet这对于使用不匹配任何内容的 glob 调用 FSL 的where尤其有效rm。有趣的是，它会抛出“目录存在”（当不存在时）而不是 IO 错误。

bet 002_mprage_hpf 002_mprage_hpf_brain -m -f 0.1
# /bin/rm: cannot remove '002_mprage_hpf_brain_tmp*': Is a directory.
[ $? -ne 0 ] && echo failed
# failed

对比

touch 002_mprage_hpf_brain_tmp_hackyhackhack
bet 002_mprage_hpf 002_mprage_hpf_brain -m -f 0.1
[ $? -ne 0 ] && echo failed
# $? == 0
