由于 raid.cksum.bad.file.block 错误， WAFL 用户数据块不一致
适用场景
- ONTAP 9
- 多种型号的磁盘
问题描述
- 多个磁盘和型号报告中等错误。示例：
[node_name: disk_server_0: disk.ioMediumError:notice]: Medium error on disk 0a.01.1: op 0x2f:0cf77000:0400 sector 217542656 SCSI:medium error - - If the disk is in a RAID group, the subsystem will attempt to reconstruct unreadable data...
- 块校验和错误，
raid_multierr_bad_block_1或raid_tetris_media_err_1报告消息。示例：
node_name ERROR raid.cksum.bad.file.block: Reading bad block on volume vol_name, Disk /aggr/plex0/rg0/0a.00.1 Shelf 0 Bay 1 (...) UID [...], disk block 24668672,...
- 因此触发了WAFL不一致。示例：
[node_name: wafl_exempt07: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 16039896320 (vvbn:1028691064 fbn:2137234048 level:0) in public inode (fileid:96 snapid:0 file_type:15 disk_flags:0x8402 error:120 raid_set:1) in volume vol_name...
