----- Original Message ----- | 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 .

This has happened once to be with a Dell Equallogic firmware update. Are you mounting the devices using a device name or using device labels? If the former you should use labels if you created them or the UUID. If you have a look in /dev/disk you'll see all the options available to your OS. If you choice to go with UUID then have a look in /dev/disk/by-uuid to get the path -- James A.
