*Toshiba* is certainly allowed (cf. line 4480 of sd.c). It's pretty natural
for a user to think they were getting shell semantics which they are not. *
has to be the first and last character but I don't think that's the issue here.
The behavior is the same if the string is "Toshiba External USB 3.0".
>From my notes:
# echo ::sd_state | mdb -k | egrep '(^un|_blocksize)'
un 3: ffffff0148254cc0
un_sys_blocksize = 0x200
un_tgt_blocksize = 0x1000
un_phy_blocksize = 0x200
un_f_tgt_blocksize_is_valid = 0x1
Rebooted system
# echo ::sd_state | mdb -k | egrep '(^un|_blocksize)'
un 3: ffffff0140e28d00
un_sys_blocksize = 0x1000
un_tgt_blocksize = 0x1000
un_phy_blocksize = 0x200
un_f_tgt_blocksize_is_valid = 0x1
Notice that un_sys_blocksize gor reset, but NOT un_phy_blocksize.
un_phy_blocksize is being used to set ashift. I *think* what's happening is
that some ioctl operations are failing forcing the code to default to ashift=9.
My 3 TB disk is giving me 26-27 MB/s write speed, so it's working rather well
despite the misalignment. But I'm just storing zballs created by "zfs send |
gzip"
Have Fun!
