I have a LVM with 2 ISCSI disk mounted. The partition started presents problem such " i/o error". I unmounted the device, and restarted target server in scsi, wich as having some problems. After that i mapped iscsi and trying to mount partition again but: When i run the pvdisplay i get the following erro:
read failed after 0 of 4096 at 0: Input/output error
And cannot mount partition.

First the very basic:
Can you ping the target (iscsi server)?
Is the target in your iscsi target list: "iscsiadm -m session"?
Hello, thanks for the help.
Yes
And the commands to discovery iscsi results ok
Such iscsiadm --mode discovery --type sendtargets
And
scsiadm -m node -T
And the disks appear on pvdisplay

Ok. [Try not to top-post]
Let's try to read your disks (replace /dev/sdX with the name of the iscsi disk):
dd if=/dev/sdX count=1 >/dev/null
dd if=/dev/sdX count=1024 >/dev/null
(please, copy the output and error(s))

I'm using gmail and searching on google i did not find how to not top-post. :( Sorry i'm new on mailists.
Thanks for your patience.
I have 2 Physical volume(in a ISCSI mounting a Volume group. For some reason the server lost communication with iscsi and when it backs the lvm "crash" with i/o error. And when i try to remount i ger the error:
mount: you must specify the filesystem type
When i run the pvdisplay i get the following erro:
read failed after 0 of 4096 at 0: Input/output error
I run commands for boths disks.
dd if=/dev/sdf count=1 >/dev/null 1+0 registros de entrada 1+0 registros de saída 512 bytes (512 B) copiados, 0,00208968 s, 245 kB/s
dd if=/dev/sdg count=1 >/dev/null 1+0 registros de entrada 1+0 registros de saída 512 bytes (512 B) copiados, 0,00203979 s, 251 kB/s
dd if=/dev/sdf count=1024 >/dev/null 1024+0 registros de entrada 1024+0 registros de saída 524288 bytes (524 kB) copiados, 0,0457182 s, 11,5 MB/s
dd if=/dev/sdg count=1024 >/dev/null 1024+0 registros de entrada 1024+0 registros de saída 524288 bytes (524 kB) copiados, 0,0163593 s, 32,0 MB/s
But if i run *mkfs* i'll lost all data?
