Hi to all.

 

I'm having problems with ZFS Snapshot 6.12.10 because have directory with non utf8 character, and when I doing the Snapshot create a temporaly files with error that finished in _temp.

 

I see for other publications that the problem its the UTF8 codification in ZFS, that have a property utf8only=on, that need to create another dataset with uft8only=false, but when I created with "zfs create -o utf8only=off pool_name/new_dataset" or similar "zpool create -o utf8only=off pool_name /path/to/disks" "zfs create -o normalization=formD pool_name/new_dataset" and later use "zfs get utf8only pool_name/new_dataset" to see the property it's created with otf8only=on, and the error in snapshot continue.
 

How I can change to utf8only=false/off to avoid problem in Snapshot?

I believe this should work, can you post an actual example?

Hmm, it works for me:

 

 

Do you have normalization set to none? I believe that's required to be possible to disable utf8only.

No, How I do?

 

with this? "zfs create -o normalization=formD pool_name/new_dataset"

 

 

Now with this "work" I test with the Snapshot If have error now with utf8 in off

the dataset converter continues to fail with normalization to none and utf8 off

 

 

Creating and populating new dataset disk3/test/a/tést...
cannot create 'disk3/test/a/tést: invalid character '�' in name

 

cannot create 'disk3/test/a/[Ñ] ': invalid character '[' in name

 

Any solution to this?

Post the output of

zfs get all pool/dataset

The Output, thx for repply

I missed that it still happened with both disabled, but AFAIK those properties only control what you can write inside the dataset, the dataset name itself cannot have any special characters.

Sorry what its AFAIK? 

 

Is there no way for the dataset to have special characters in the name to take snapshots? I was seeing that in the next version 6.13 it will have snapshot natively, but I couldn't find a beta to test, do you know if snapshots with special characters will be allowed in this version?

 

Thx Best Regards

Not as far as I know (AFAIK)

https://docs.oracle.com/cd/E26505_01/html/E37384/gbcpt.html

 

Each ZFS component, such as datasets and pools, must be named according to the following rules:

Each component can only contain alphanumeric characters in addition to the following four special characters:

Underscore (_)

Hyphen (-)

Colon (:)

Period (.)

Pool names must begin with a letter, and can only contain alphanumeric characters as well as underscore (_), dash (-), and period (.). Note the following pool name restrictions:

The beginning sequence c[0-9] is not allowed.

The name log is reserved.

A name that begins with mirror, raidz, raidz1, raidz2, raidz3, or spare is not allowed because these names are reserved.

Pool names must not contain a percent sign (%).

Dataset names must begin with an alphanumeric character.

Dataset names must not contain a percent sign (%).

In addition, empty components are not allowed.

Ok,  I will mark that solved
