WARNING: Read Failed. group:1 disk:0 AU:682752 offset:8192 size:4096

表示读到682752 这个au的时候，出问题，不是说你的au总数

sunstar3000

感谢版主解答，LUN的可用性有问题 可以理解为块有损坏吗?这个问题有解决的可能性吗。

Read Failed. group:1 disk:0 AU:682752,raw1最大为583435，AU为682752这个是什么原因

/dev/raw/raw1 IO 失败造成DDD DISKGROUP 过多ASM DISK OFFLINE，造成DDD DISKGROUP 强制DISMOUNT


该问题应当与你的LUN的可用性有问题
