SVRF—Object Store Verify Fail
Each time content is read from or written to disk, several verification
and integrity checks are performed to ensure data being sent to the
requesting user is identical to the data originally ingested into the
system. If any of these checks fail, the system automatically removes
the corrupt data to prevent it from being retrieved again.
When a content block fails the verification process, this message is
issued.
The “SVRF - Object Store Verify Fail” audit message should be monitored
closely. It means a given content block failed verification checks, which can
indicate attempts to tamper with content or impending hardware failures.
SVRU—Object Store Verify Unknown
The Local Distribution Router (LDR) storage component continuously
scans all files in the object store to schedule content verification. If it
detects a file or directory does not match expected naming conven-
tions, it moves the unexpected file(s) to the “garbage” directory, where
they can be automatically or manually removed (depending on LDR
configuration).
