Cache creation failed: get_device for cache device failed. #32

Closed Poisonsting closed 6 years ago

Poisonsting commented 6 years ago

After finally finding the offending copy of eio_cli that was causing the max int issue, I've run into a new problem. When running this command:

eio_cli create -d /dev/sdc -s /dev/sda1 -p lru -m wb -c btrfsCache

I'm presented with the following output:

Cache Name : btrfsCache Source Device : /dev/sdc SSD Device : /dev/sda1 Policy : lru Mode : Write Back Block Size : 4096 Associativity : 256 Cache creation failed (dmesg can provide you more info)

dmesg provides this line:

[1245882.920180] enhanceio: Cache creation failed: get_device for cache device failed.

EIO tries to open cache device exclusively. Please, make sure, that /dev/sda1 exists and is not open by someone else (i.e., it is not configured as PV, not mounted etc.)

I've tried completely wiping the partition table on /dev/sda and starting from scratch, same error.

Nobody else confirmed there is an issue, closing it for now. If someone runs into it again, feel free to reopen, with some more info preferably. Thanks.
