NexentaStor 翘掉一例


判断应该是磁盘负载过重,导致 NexentaStor 并 ESXi 一起死掉。


该系统配置变量控制设备 I/O 队列大小 (I/O 并发性)。
This system configuration variable controls device I/O queue size (I/O concurrency).

对于 SATA 磁盘,建议值为 ‘1’。
For SATA disks, the recommended value is ‘1’.
For all other disk types, please keep the system default.

请注意,调整此参数可能会影响 I/O 延迟,也许会以原始流吞吐量为代价。
Note that tuning this parameter may affect I/O latency, possibly at the expense of raw streaming throughput.
