问题描述

  • 卷上报告了 WAFL 不一致,并且在事件日志中看到以下警报:

[Node-01: wafl_exempt04: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 1234567890 (vvbn:12345670 fbn:0 level:0) in public inode (fileid:222222 snapid:111 file_type:1 disk_flags:0x8002 error:121 raid_set:1) in volume vol_1@vserver:9b3XXXX-97XX-11XX-a2XX-000dXXXXXXXa.
[Node-01: wafl_exempt04: wafl.incons.userdata.vol:alert]: WAFL inconsistent: volume vol_1@vserver:9b3XXXX-97XX-11XX-a2XX-000dXXXXXXXa has an inconsistent user data block. Note: Any new Snapshot copies might contain this inconsistency.
[Node-01: wafl_exempt04: callhome.wafl.inconsistent.user.block:alert]: Call home for WAFL INCONSISTENT USER BLOCK

  • WAFL 无法恢复被标记为伪坏块 (E_PSEUDOBAD_BLOCK) 的块。因此,WAFL 将文件系统标记为不一致,以防止进一步的数据损坏。
  • 损坏仅限于报告的卷,没有 RAID 或聚合级别错误的迹象。这表明问题仅限于特定卷,不会影响更广泛的级别。
