我正在评估使用两台现成服务器构建廉价iSCSI冗余SAN的可能性.我们的想法是运行
linux,pacemaker和iSCSI目标 – 类似于
SAN Active-Passive on linux-ha-examples.
当我阅读时,同一页面让我有点害怕：
During the switchover of the iscsi-target one can detect a gap in the
protocol of write-test.log. In our setup we observed a delay of 30s.
There are problems reported in connection of ext3 and an iscsi
failover This configuration has been tested with ext2 and ext3 and
worked with both filesystems.
有没有人投入生产由linux机箱制造的冗余iSCSI SAN？故障转移事件真的那么糟糕吗？ I / O冻结30秒对我来说听起来像是一场灾难,不是吗？
