從昨天開始 linux 通過光纖直接連接磁盤陣列，會出現(xiàn)磁盤陣列掉了的情況，然后機(jī)器會重啟，本來重啟后，rose ha 會自動掛載磁盤陣列，現(xiàn)在由于 rose ha 也出了點(diǎn)問題，導(dǎo)致不切換備用服務(wù)器，主服務(wù)器也不掛載磁盤陣列的情況。導(dǎo)致服務(wù)起不來。

目前報錯如下 EXT4-fs error (device sdb): ext4_read_block_bitmap: Cannot read block bitmap -

我去磁盤陣列查看了下，當(dāng)時磁盤陣列也有報錯 大約報錯是 光纖連接中斷一分鐘這樣的錯誤

請教下大神，這是什么問題？光纖線 連接的問題嗎？還是其他問題？
