[zfs-discuss] Force SATA1 on AOC-SAT2-MV8

2007-11-02 Thread Eric Haycraft
I have a supermicro AOC-SAT2-MV8 and am having some issues getting drives to work. From what I can tell, my cables are to long to use with SATA2. I got some drives to work by jumpering them down to sata1, but other drives I can't jumper without opening the case and voiding the drive warranty.

I have a 9-bay JBOD configured as a raidz2. One of the disks, which is on-line and fine, needs to be swapped out and replaced. I have been looking though the zfs admin guide and am confused on how I should go about swapping out. I though I could put the disk off-line, remove it, put a new

Chris, You need to use the zpool replace command. I recently enhanced this section of the admin guide with more explicit instructions on page 68, here: http://opensolaris.org/os/community/zfs/docs/zfsadmin.pdf If these are hot-swappable disks, for example, c0t1d0, then use this syntax: #

Jumpering drives by removing the cover? Do you mean opening the chassis because they aren't removable from the outside? Your cable is longer than 1 meter inside of a chasis?? I think sataI is 2 meters and sataII is 1 meter. As far as a system setting for demoting these to sataI I don't know,
