Hi All, We have developed a RAID creation application which create RAID with Ddf RAID metadata. We are using PCIe ssd as physical disks. We are writing the anchor, primary, secondary headers, virtual and physical records, configuration record and physical disk data. The offsets of the headers are updated in the primary, secondary and anchor headers correctly. The problem is when we try to boot to Ubuntu server and we observe that mdadm is throwing a disk failure error message and from block layer we are getting rw=0, want=7, limit=1000215216. We also confirmed using there is no I/O error is coming from the PCIe ssd, using a logic analyzer. Also the limit value 1000215216 is the capacity of the ssd in 512 byte blocks. Any insight will be highly appreciated.
