NAME¶
s3ql_verify - Verify data in an S3QL file system
SYNOPSIS¶
s3ql_verify [options] <storage url>
DESCRIPTION¶
S3QL is a file system for online data storage. Before using S3QL, make sure to
consult the full documentation (rather than just the man pages which only
briefly document the available userspace commands).
The
s3ql_verify command verifies all data in the file system. In contrast
to
fsck.s3ql,
s3ql_verify does not trust the object listing
returned by the backend, but actually attempts to retrieve every object. It
therefore takes a lot longer.
The format of
<storage url> depends on the backend that is used.
The S3QL User's Guide should be consulted for a description of the available
backends.
OPTIONS¶
The
s3ql_verify command accepts the following options.
- --debug-modules <modules>

- Activate debugging output from all S3QL modules. Debug messages will be
written to the target specified by the --log option.
