https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219760 Bug ID: 219760 Summary: ZFS iSCSI w/ Win10 Initiator Causes pool corruption Product: Base System Version: 11.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: henric_jungheim@yahoo.com Created attachment 183182 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D183182&action= =3Dedit dmesg With a zvol to provide a 1TB iSCSI drive for a Windows 10 initiator, using "Create a system image" causes the pool to be corrupted. Neither drive rep= orts any SMART problems (both have "SMART overall-health self-assessment test result: PASSED"). The backup completes without errors on the Windows side. The iSCSI volume is set for 64k blocks and that is also the NTFS cluster si= ze.=20 The backup is from two SATA SSDs in a laptop and done over a Gigabit Ethern= et link. Bitlocker is enabled for the backup volume on the Windows side, which could possibly alter the disk access patterns...?=20=20 Deleting the zvol, clearing the error, and retrying the backup to a new zvol causes the same problem. The first try used "FreeBSD 11.0-STABLE #10 r3175= 13: Thu Apr 27 12:09:34 MST 2017". I updated to "FreeBSD 11.1-PRERELEASE #11 r319488: Thu Jun 1 21:12:33 MST 2017" for the second try. pool: tank state: DEGRADED status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://illumos.org/msg/ZFS-8000-8A scan: scrub repaired 0 in 9h34m with 0 errors on Fri Jun 2 22:36:45 2017 config: NAME STATE READ WRITE CKSUM tank DEGRADED 0 0 74 mirror-0 ONLINE 0 0 0 gpt/tank0 ONLINE 0 0 0 gpt/tank1 ONLINE 0 0 0 mirror-1 DEGRADED 0 0 148 gpt/tank0b DEGRADED 0 0 148 too many errors gpt/tank1b DEGRADED 0 0 148 too many errors errors: Permanent errors have been detected in the following files: tank/iscsi/mcp2:<0x1> NAME PROPERTY VALUE SOURCE tank/iscsi/mcp2 type volume - tank/iscsi/mcp2 creation Fri Jun 2 12:49 2017 - tank/iscsi/mcp2 used 1.00T - tank/iscsi/mcp2 available 3.22T - tank/iscsi/mcp2 referenced 971G - tank/iscsi/mcp2 compressratio 1.00x - tank/iscsi/mcp2 reservation none default tank/iscsi/mcp2 volsize 1T local tank/iscsi/mcp2 volblocksize 64K - tank/iscsi/mcp2 checksum skein inherited from tank tank/iscsi/mcp2 compression off local tank/iscsi/mcp2 readonly off default tank/iscsi/mcp2 copies 1 default tank/iscsi/mcp2 refreservation 1.00T local tank/iscsi/mcp2 primarycache all default tank/iscsi/mcp2 secondarycache all default tank/iscsi/mcp2 usedbysnapshots 0 - tank/iscsi/mcp2 usedbydataset 971G - tank/iscsi/mcp2 usedbychildren 0 - tank/iscsi/mcp2 usedbyrefreservation 57.2G - tank/iscsi/mcp2 logbias latency default tank/iscsi/mcp2 dedup off default tank/iscsi/mcp2 mlslabel - tank/iscsi/mcp2 sync standard default tank/iscsi/mcp2 refcompressratio 1.00x - tank/iscsi/mcp2 written 971G - tank/iscsi/mcp2 logicalused 970G - tank/iscsi/mcp2 logicalreferenced 970G - tank/iscsi/mcp2 volmode default default tank/iscsi/mcp2 snapshot_limit none default tank/iscsi/mcp2 snapshot_count none default tank/iscsi/mcp2 redundant_metadata all default Geom name: ada3 modified: false state: OK fwheads: 16 fwsectors: 63 last: 11721045127 first: 40 entries: 152 scheme: GPT Providers: 1.
