Hello I have this problem: Yesterday server with FreeBSD 6.0 was self restarted . In messages was this: Mar 8 20:03:11 mail kernel: ar1: WARNING - mirror protection lost. RAID1 array in DEGRADED mode Mar 8 20:03:11 mail kernel: ar1: writing of Intel MatrixRAID metadata is NOT supported yet Mar 8 20:03:11 mail kernel: subdisk8: detached Mar 8 20:03:11 mail kernel: ar1: writing of Intel MatrixRAID metadata is NOT supported yet Mar 8 20:03:11 mail last message repeated 78 times Mar 8 20:03:11 mail kernel: ad8: detached Mar 8 20:03:11 mail kernel: unknown: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=326028767 Mar 8 20:04:39 mail syslogd: kernel boot file is /boot/kernel/kernel Mar 8 20:04:39 mail kernel: Copyright (c) 1992-2005 The FreeBSD Project.

What does it mean? Bad disk,board, FreeBSD : () ? In this moment on ar1 was written some big backup. Thanks John
