Greetings,
I'm trying out a 3TB SATA drive in one of those SATA-dock units
which plugs into either an eSATA port or a USB port. The drive
works as I'd expect when connected to my 64-bit oi151a7 machine
via eSATA, I can "zpool create", etc., normally, seeing the full
capacity of the drive.
However, if I use USB, some problems show up. This particular unit
claims to support up to 4TB drives, and things like "fdisk", "rmformat -l",
and "format -e" show a label describing all 3TB. However, there are a
lot of these warnings in /var/adm/messages:
Dec 9 14:50:18 myhost scsi: [ID 107833 kern.warning] WARNING:
/pci@0,0/pci1028,2da@1d/hub@1/storage@4/disk@0,0 (sd13):
Dec 9 14:50:18 myhost Request rejected: too large for CDB:
lba:0x15d506110 len:0x00000010
I'm able to "zpool import" a pool via USB that was created via eSATA,
despite the above messages, and the pool ("zfs list", etc.) appears
to be the right size. But a "zdb -l" can only read the first two
labels from the drive when connected by USB, failing to read the
last two (and said failures correspond with new instances of the
above warnings appearing in /var/adm/messages).
I should also mention that the same error messages occur when connected
by USB to a machine running XStreamOS Desktop beta-3, which is a much
fresher release of illumos than my old oi151a7 system.
So, I'm curious if others have seen this with >2TB drives connected
by USB to illumos-based systems. It's possible that I've just got a bad
USB-to-SATA device here, and if so, I'd appreciate hearing of specific
devices that others have had success with in connecting these larger
drives via USB to illumos.
Thanks and regards,
Marion
