@burnbum55 welcome to the Rockstor community.
You unfortunately selected a RAID level that has been flagged as unsupported in the upstream distro (i.e. SUSE SLES → Leap/TW). So, while it is recognized, by default the file system is only mounted as read-only, making it impossible to create shares.
For reference:
A similar conversation happened here:
Finally, the other option under the current official Rockstor version (e.g. 4.5.8-0) is to install the kernel backport and take advantage of the e.g. RAID10c3, or, in conjunction with the above “unsupported” setting take one of the RAID5/6 options into account.
See here:
https://rockstor.com/docs/howtos/stable_kernel_backport.html
Depending on where your RAID5 pool came from (i.e. imported into Rockstor from another server vs. created without any data within Rockstor, etc.), this might be of interest to you, as well:
Without getting into the whole philosophical debate on whether btrfs RAID5/6 is “stable and safe enough” for the home user, it’s still possible to work with RAID5/6 if you really want to. You can enable “unsupported btrfs” functionality by enabling them as described in the section above the above linked capability matrix.
Some file system features are available in SUSE Linux Enterprise Server 15 SP3 but are not supported by SUSE. By default, the file system drivers in SUSE Linux Enterprise Server 15 SP3 will refuse mounting file systems that use unsupported features (in particular, in read-write mode). To enable unsupported features, set the module parameter
allow_unsupported=1in/etc/modprobe.dor write the value1to/sys/module/MODULE_NAME/parameters/allow_unsupported.
@phillxnet anything you want to add, adjust?
