https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224037 --- Comment #7 from Petr Leszkow <petr@leszkow.eu> --- btw, just checked SCSI Asignment at http://www.t10.org/lists/asc-num.htm#ASC_27 for ASC 27,0 ...see list bellow: so, I think it would be sufficient if kernel can instruct the cam or any upper layer to do not attempt to mount devices with ASC 27,0 and 27,1 as RW and handle them for example as CD/DVD asc 27,4 asc 27,5 ? What do you think ? Thanks. Petr D - Direct Access Block Device (SBC-4) Device Column key .Z - Host Managed Zoned Block Device (ZBC) --------------------- .
