I am using a Asrock motherboard and a LSI Megaraid controller I wanted to connect 4 drives to my LSI Raid controller and 1 drive to my motherboard. This would make it possible for me to run 2 x 5 drives in Raid-Z. But.. When I do this and begin copying to the Raid-Z it will copy some GBs before the computer begins stuttering and stops copying (Stutter keeps on going) and it wont go any further and a reboot is necesary. If I run a 4 way Raid-Z using only the LSI controller then it runs fine, so its by combining the 2 different controllers. The exact hardware is AMD Phenom X3 K10N78FullHD-hSLI R3.0 which has a Nvidia N8200 chipset 4 x 2GB Kingston HyperX ram LSI MegaRAID SAS 8308ELP -- Med venlig hilsen/Kind Regards.

some time out if they don''t have updated firmware On Fri, Sep 11, 2009 at 11:57 AM, Volker A. Brandt <vab at bb-c.de> wrote:> > Seagate 1.5 TB drives? > > This sounds somewhat ominous.

I thought they were all just first generation hiccups and solved with current firmware. So should we stay away from all 1.5TBs, or just from these Seagates?

The workload is bursty - mostly MDA driven code generation and compilation of > 1M KLoC applications and they work well enough for that. Also by now probably a PetaByte of zfs send/recvs and many scrubs, never a timeout and never a checksum error. They are all rev CC1H. So your mileage may vary, as they say... Cheers -- Frank

So your mileage may vary, as they say...I''we also been running three of them with SD17 in a raidz for about a year without any problems at all.
