Receiving "device-mapper: create ioctl failed: Device or resource busy" after adding storage to a RHEL5 server
Issue
- Adding additional disk to a server, going from 123 to 152 luns through a dual-ported HBA. Once new storage was seen on the server and the disks partitioned, a reboot causes errors from device-mappers after udev rules are started.
- Allocated ~150 LUNs
Environment
- Red Hat Enterprise Linux 5.4 or earlier
- Red Hat Enterprise Linux 5.9
- kpartx-0.4.7-30 or earlier
