I have an iscsistorage which I attached to a new CentOS 6.3 server. I
added logic volumes as usual, the block devices (sdb & sdc) showed up in dmesg; I can mount and access the stored files.
Now we did an firmware software update to that storage (while unmounted/detached from the fileserver) and after reboot of the storage and reatache the iscsi nodes I do get new devices. (sdd & sde)
The last time I remember a simple vgchange -ay changed all neede settings so that I can mount and use the volumes as expected.
But this time I do get an IO error like
/dev/sun7110to_dali_LUN_3/lvol0: read failed after 0 of 4096 at
1 logical volume(s) in volume group “sun7110to_dali_LUN_3” now active
What might be messed up? What can I try do get the storage/filesystems back online?
Thanks for any sugesstion and regards . G
