1314482 – Inconsistent headings in 'lvs' output for cache

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jonathan Earl Brassow 2016-03-03 17:31:39 UTC

[root@bp-01 ~]# lvs -o name,cache_mode,cache_policy,cache_dirty_blocks vg
  LV   Cachemode    Cache Policy CacheDirtyBlocks
  lv   writethrough cleaner                     0

Three different header types: Cachemode, Cache Policy, CacheDirtyBlocks

Should be: CacheMode, CachePolicy, CacheDirtyBlocks

Comment 1 Jonathan Earl Brassow 2016-03-03 17:32:46 UTC

While I'm at it...

[root@bp-01 ~]# lvs -o barf 2>&1 | grep cache
    lv_metadata_size       - For thin and cache pools, the size of the LV that holds the metadata.
    data_lv                - For thin and cache pools, the LV holding the associated data.
    metadata_lv            - For thin and cache pools, the LV holding the associated metadata.
    cache_total_blocks     - Total cache blocks.
    cache_used_blocks      - Used cache blocks.
    cache_dirty_blocks     - Dirty cache blocks.
    cache_read_hits        - Cache read hits.
    cache_read_misses      - Cache read misses.
    cache_write_hits       - Cache write hits.
    cache_write_misses     - Cache write misses.
    cachemode              - For cache pools, how writes are cached.
    cache_policy           - The cache policy (cached segments only).
    cache_settings         - Cache settings/parameters (cached segments only).


'cachemode' should be 'cache_mode'
