My major concern is the failure of drives, not so much the hot-swapping. I can live with taking the machine offline, replacing the drive(s), and booting up. Yanking the drives out from live system is the only way I can simulate a hard failure. Without this working, I cannot be sure the system will remain running should a drive go bad. I'm not sure how the system would handle this given ahd cannot handle pulling of hot drives out. I will try to get in touch with the driver maintainer. Thanks again! -Simon On Wed, 2 May 2012 17:21:14 -0500, Mark Felder wrote: >On Wed, 02 May 2012 17:06:04 -0500, wrote: >> >> Having said the above, is there any FreeBSD RAID software I can use with >> ahb driver that won't give me same issues I'm experiencing with ahd and >> ZFS? >> vinum? gmirror?
