I have a RAID 1 that was working fine without errors reported. The RAID was not on Degraded state. When i shutdown Freenas, GEOM_MIRROR start to report errors during shutdown. I’ve checked SMART and there are no problems with the disks. During shutdown: Sep 10 07:33:15 kernel: ad6: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=976773167 Sep 10 07:33:20 kernel: ad6: TIMEOUT - WRITE_DMA48 retrying (0 retries left) LBA=976773167 Sep 10 07:33:25 kernel: ad6: FAILURE - WRITE_DMA48 timed out LBA=976773167 Sep 10 07:33:25 kernel: GEOM_MIRROR: Cannot write metadata on ad6 (device=raid1, error=5). Sep 10 07:33:25 kernel: GEOM_MIRROR: Cannot update metadata on disk ad6 (error=5). Sep 10 07:33:32 kernel: ad7: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=976773167 During startup: Sep 10 07:47:47 kernel: ad6: 476940MB <WDC WD5000AAKB-00YSA0 12.01C02> at ata3-master UDMA100 Sep 10 07:47:47 kernel: ad7: 476940MB <WDC WD5000AAKB-00YSA0 12.01C02> at ata3-slave UDMA100 Sep 10 07:47:47 kernel: GEOM_MIRROR: Device raid1 created (id=3401427605). Sep 10 07:47:47 kernel: GEOM_MIRROR: Device raid1: provider ad7 detected. Sep 10 07:47:47 kernel: GEOM_MIRROR: Device raid1: provider ad6 detected. Sep 10 07:47:47 kernel: GEOM_MIRROR: Component ad6 (device raid1) broken, skipping. Sep 10 07:47:47 kernel: GEOM_MIRROR: Device raid1: provider ad7 activated. Sep 10 07:47:47 kernel: GEOM_MIRROR: Device raid1: provider mirror/raid1 launched. If i try to insert disk “ad6” in the mirror: Sep 10 07:49:40 kernel: GEOM_MIRROR: Component ad6 (device raid1) broken, skipping. Sep 10 07:49:40 kernel: GEOM_MIRROR: Cannot add disk ad6 to raid1 (error=22). The only solution was rebuild the mirror. Why this errors? Best Regards, Martinho.
