OpenZFS on OS X

HI, I recently moved my dropbox folder to my ZFS volume. Whenever I save changes to a file, the file name becomes all lower case letters, for example "File.txt" will become "file.txt" This did not occur when my dropbox was on my HFS+ volume. Both my ZFS and HFS+ volumes were formatted as case-insensitive. This doesn't seem to occur with files on my ZFS volume that aren't in my dropbox. Just wondering if anyone knew the cause for this error.

Also, if I rename a file on my ZFS volume (not in my dropbox) from upper case to lower case, I get the error message "The operation can't be completed, an unexpected error occurred (error code -43)." The rename is successful though.

Thanks

Hi,

Interesting situation! I have my dropbox on ZFS, and am not experiencing what you describe. My user is in dataset tank/Users.

Please check:

Code: Select all

zfs get all tank/Users
tank/Users  casesensitivity             insensitive                                     -


and a brief peek inside my dropbox:

Code: Select all

cd Dropbox/
jerry:Dropbox brendy$ ls -l
total 33666

Also checked renaming files by case, no problem.

Thanks for the info. I confrmed my zfs volumes are case insensitive. I created my zfs volume as a mirrored volume with the command listed on the openzfs on osx wiki page

"sudo zpool create -f -o ashift=12 -O casesensitivity=insensitive -O normalization=formD $poolname mirror diskX diskY"

Regarding the code 43 error when renaming files from upper case to lower case, I confirmed it occurs with any zfs volume. As an experiment, I formatted a USB flash drive to zfs using the following command a few minutes ago:

"sudo zpool create -f -o ashift=12 -O casesensitivity=insensitive -O normalization=formD zfsflash disk8"

I then copied an excel file to a folder on the flash disk, and got the code 43 error when renaming the file to lower case letters. Interestingly, when I rename files from lowercase to uppercase, or uppercase to lowercase, it often takes 2 tries for it to succeed, but each time it successfully changes to lowercase, the error 43 box pops up.

I'm running OSX 10.11.6

Thanks

Interesting....What version of O3X?

Hello,

was there ever a resolution of this issue? I have exactly the same problem with zfs and Dropbox.

Here is another data point, copying a file with camel-case name to the zfs filesystem, which is part of my Dropbox folder:

Code: Select all

$  cp ~/Dropbox/AbstractSebastianWhite.pdf ./
$ ls -l
total 1
-rw-r--r--@ 1 bauerdic  staff  22430 Mar 27 16:45 abstractsebastianwhite.pdf
$  tree .
.
└── AbstractSebastianWhite.pdf

0 directories, 1 file


The ls command tells me the file name is all lower case, while tree thinks it has camel-case.

Finder tells me that file only has lower case. The Dropbox web interface thinks it has camel-case.

Also, zsh autocompletion thinks the file name is camel-case. Weird and a bit scary.

It would be great if we could use zfs file systems for dropbox, but not at the moment!

Best regards, Lothar Bauerdick

I've just started seeing this same issue. I'm running a slightly later version of 1.6.1 form master and my Dropbox has been working fine for a couple of months since I set it up on a ZFS (case insensitive dataset) but just today I've started having the same errors as reported here - all files renamed to lower case when I copy them in to the DropBox folder and an error if I try and re-name them again.
