Hello, context: amd64, FreeBSD 12.0-ALPHA1 #0 r337682, ZFS. The system is *not* root-on-zfs. It boots to an SSD. The three disks indicated below are spinning rust. NAME STATE READ WRITE CKSUM storage ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 ada1 ONLINE 0 0 0 ada2 ONLINE 0 0 0 ada3 ONLINE 0 0 0 This machine was running 11.2 up until about a month ago. Recently I've seen this flash up on the screen before getting to the beastie screen: BIOS drive C: is disk0 BIOS drive D: is disk1 BIOS drive E: is disk2 BIOS drive F: is disk3 BIOS drive G: is disk4 BIOS drive H: is disk5 BIOS drive I: is disk6 BIOS drive J: is disk7 [the above is normal and has always has been seen on every boot] read 1 from 0 to 0xcbdb1330, error: 0x31 read 1 from 0 to 0xcbdb1330, error: 0x31 read 1 from 0 to 0xcbdb1330, error: 0x31 read 1 from 0 to 0xcbdb1330, error: 0x31 read 1 from 0 to 0xcbdb1330, error: 0x31 read 1 from 0 to 0xcbdb1330, error: 0x31 read 1 from 0 to 0xcbdb1330, error: 0x31 read 1 from 0 to 0xcbdb1330, error: 0x31 the above has been happening since upgrading to -current a month ago ZFS: i/o error - all block copies unavailable ZFS: can't read MOS of pool storage the above is alarming and has been happening for the past couple of days, since upgrading to r337682 on the 12th August. The beastie screen then loads and it boots normally. Should I be concerned? Is the output indicative of a problem? thanks, -- J.Received on Tue Aug 14 2018 - 17:37:27 UTC
