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?
