I found that the script is old and using old style syntax for mdb, so now trying to find the right syntax.
Just working my way through this, perhaps there's a better way. ::zfs_params cause SIGSEGV in mdb ... ... metaslab_gang_bang = 0x20001 zio_injection_enabled = 0x0 zvol_immediate_write_sz = 0x8000 *** mdb: received signal SEGV at: [1] 1() invalid frame (1) mdb: (c)ore dump, (q)uit, (r)ecover, or (s)top for debugger [cqrs]? -- This message posted from opensolaris.org
