So my question is: what's the > proper way of doing de attach/detach operation ? > I did a fresh install then turned the machine off and removed on disk. It booted again just fine. Then I turned it off again and inserted the disk I had removed. Now it will panic: panic: softdep_setup_inomapdep: found inode cpuid = 0 boot() called on cpu#0 Uptime: 2s If I removed the disk and boot again it will work and show the following message: ar0: 152627MB <ATA RAID1 array> [19457/255/63] status: DEGRADED subdisks: disk0 READY on ad4 at ata2-master disk1 DOWN no device found for this disk How can I replace a failed disk with this setup ? Given what I've read I'm not really using the controller's RAID support but only the RAID support present in the ata subsystem. Is that true ? In the BIOS I don't have any arrays.
