https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D192050 Bug ID: 192050 Summary: [zfs] The allowed character set for ZFS dataset names is very limited Product: Base System Version: 10.0-RELEASE Hardware: Any OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: aberg010@my.hennepintech.edu While there are very few limitations on directory names, ZFS dataset names = seem to support only alphanumeric characters and the space character. This is extremely annoying when trying to create the occasional dataset where the intended directory name has a punctuation mark such as an exclamation point= . It also does not seem to support non-ASCII characters either. With the excepti= on of @, I cannot see why a ZFS dataset name cannot support any character that= is allowed in a directory name. With this limitation, there are two workarounds: limit directory names to t= he character set allowed in dataset names, or create different dataset names a= nd explicitly set the mountpoint to have the correct name of the directory. The former is kind of absurd, but more or less manageable, depending on how bad= ly you want/need the directory name to be correct. The latter creates the need= for more complicated scripts and workflows, and extra permissions are needed for creating and mounting datasets with explicitly set mountpoints. # zfs create storage/=E6=96=87=E5=AD=97=E5=8C=96=E3=81=91 cannot create 'storage/=E6=96=87=E5=AD=97=E5=8C=96=E3=81=91': invalid chara= cter ' in name # zfs create storage/touch=C3=A9 cannot create 'storage/touch=C3=A9': invalid character ' in name # zfs create "storage/Here Today, Gone Tomorrow" cannot create 'storage/Here Today, Gone Tomorrow': invalid character ',' in name # zfs create "storage/Why?" cannot create 'storage/Why?': invalid character '?' in name I am quite curious why such a limitation exists. I would also like to know = if this is a limitation of ZFS as a whole or just zfs(8) in particular. --=20 You are receiving this mail because: You are the assignee for the bug.=
