Lpro Aio Ramdisk — Device Not Registered Hot

A: Not directly. It indicates the device failed to register, so writes to that ramdisk are likely failing silently. If your application expects the ramdisk to exist, it may crash or corrupt data. Always run fsck on any persistent data stored on that device.

If the system is low on contiguous DMA memory or has exhausted its AIO request queues, the kernel will reject new device registrations. This is common in virtualized environments (KVM, Xen) with overcommitted RAM. lpro aio ramdisk device not registered hot
