Hi, 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 1610608476160: Eingabe-/Ausgabefehler but also: 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 . Götz -- Götz Reinicke - IT-Koordinator - Filmakademie Baden-Württemberg GmbH
