STATUS_QUOTA_LIST_INCONSISTENT

The quota update buffer is internally inconsistent

Native quota updates pass one or more FILE_QUOTA_INFORMATION records in a linked buffer. Each NextEntryOffset, SID length, alignment, and total buffer length must agree. This status indicates that the file system cannot safely walk the supplied list.

It differs from a policy error such as an invalid lower limit: the request cannot yet be interpreted as a valid set of users and limits. Validate serialization before examining quota values.

What to inspect

  • Check every NextEntryOffset for required alignment and bounds.
  • Validate SID lengths and ensure the final entry has a zero next offset.
  • Use IoCheckQuotaBufferValidity in kernel code before sending the request.
