Hi, everyone.

   Have you ever happened to this issue, and how to fix it? I deployed a LVM and open-iscsi in the client and a tgt in the server. But in some circumstance LVM can't been found. Here is a steps:

1.       Stop Tgt process;

2.       The directory which a mapped device mounted is workless;

3.       Restart Tgt process, The directory is still not working;

4.       Umount the mapped virtual device, the client will blocked;

5.       Restart the client, LVM modules like pv, lv are not found anymore, but surely existed;
