CentOS

How did you create the partition, and what's the output of: fdisk -l /dev/mapper/mpathd Don't think it will make any difference; could you try XFS instead of ext4? I don't think this will work either, but it may be worth a try: - shut down the server - disconnect the FC cables - start the server an...

You said you tested it with a windows server, so you must have defined that second host and mapped it to the volume. I guess you can remove the mapping from some V3700 menu. Sorry, I've run out of ideas - the only thing I can suggest is to create a partition, format and mount it, and then test it. ...

Under "No de nodos que .." you have two, which I guess suggests that the volume is connected to two hosts. On my system the volume is connected to one host ("# Nodes Logged In"). The disk identifiers on my system (CentOS 7.5) are in this format: hhhhhhhh-hhhh-hhhh-hhhh-hhhhhhhhhhhh (h=hex digit) On...

You can find my multipath.conf in my second post (CentOS 7.5). df -Th: Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/mpatha1 ext3 15T 13T 2.3T 85% /my/file/system It's mounted with UUID in /etc/fstab. The only difference I see is that two nodes are logged in ("# Nodes Logged In"), but...

If I understand your first post correctly, the eight disks did show up before you installed multipath? If so, then it should have nothing to do with multipath -> I would start looking at the setup on the V3700. You may also want to exclude the two local disks in /etc/multipath.conf. This is correct...

Haven't seen any problems. I have two FC cables between the V3700 and the server, and I guess that's why I see two /dev/sdX. If you have eight cables, then I guess your setup is OK as well. If not, then I would try to find out why you have eight /dev/sdX. I do not also have two FC cables, but I do ...

You can show the result of the command df -Th.

And the multipath .conf file please.

So, is it normal for me to repeat the disc, even if it is the same disc? but I have no problem with the integrity of the data?

no, the partition / dev / mapper / multipathzx because before it was dev / sdX but the multipath I change that for not blocking it are logical disk the only disk per fiber is the 2.2tb in the first part is the images of the before and after if you understand me.
