[OpenIndiana-discuss] Case sensitivity "mixed" vs "sensitive"

[Cal Sawyer]

Thanks for your responses, Rich and John

In my examples, i was creating *only *new files and directories.

Further investigation shows that any dataset i create w/o specifying
casesensitivity=sensitive during zfs create defaults to "insensitive",
although the pool itself is case sensitive.  Is this intended behaviour and
if so why?

What a drag ... live and learn, huh? :)

regards,

Did you do an ls after those commands?  If a file exists, touch
won't complain.  It'll just silently do what you asked it too:
update the file's mtime to the current time.  In other words,
your touch commands might've been operating on the same file.

HTH,

Are you sure B didn't really exist prior to 'mkdir B' ?
On UNIX and POSIX file systems B and b are different.
casesensitivity=sensitive is the default POSIX behaviour.
casesensitivity=mixed is only useful if you export the filesystem using
SMB/CIFS
