https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219760 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=183182&action=edit 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 reports 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 size. The backup is from two SATA SSDs in a laptop and done over a Gigabit Ethernet link. Bitlocker is enabled for the backup volume on the Windows side, which could possibly alter the disk access patterns...? 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 r317513: 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.
