OK, in addition to my last post, upon rebooting my system (which had a raid1 device functioning flawlessly thru 2 hours of testing), I get teh following messages at boot: Starting up RAID devices. raidadd(pid 37) used obsolete MD ioctl, upgrade your software to use new ictls. raidadd(pid 37) used obsolete MD ioctl, upgrade your software to use new ictls. raidadd(pid 37) used obsolete MD ioctl, upgrade your software to use new ictls. Am I missing something? Again, I am running RH5.2, 2.0.36 with the raid0145-19990108-2.0.36 patch and raidtools-0.90 (the 1214 version I think). Thanks Chris
