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 2014-07-14 14:15:34 UTC 
This is a tracking bug for required LVM Cache features
Comment 1 Jonathan Earl Brassow 2014-07-14 23:07:17 UTC 
Features necessary to remove from tech preview and turn on by default upstream:
- ability to check and repair Cache LVs (i.e. their metadata LV)
- ability for cache to work on RAID LVs

Other features needed at some point:
- resize Cache data LV (w/o removing and recreating cache LV)
- resize Cache metadata LV (w/o removing and recreating cache LV)
- ability to change cache policy (w/o removing and recreating cache LV)
- ability to change cache mode (w/o removing and recreating cache LV)
- cache profiles
Comment 2 Alasdair Kergon 2014-07-14 23:10:22 UTC 
The requirement for turning on upstream is a lot narrower: it is that all commands it is possible for a user to run EITHER function correctly OR give a controlled error.  There are bug reports indicating a user trying snapshots gets into a mess very easily.
Comment 3 Jonathan Earl Brassow 2014-07-14 23:38:50 UTC 
I will split the top group from 'remove tech preview and turn on by default upstream' to 'remove from tech preview'  and 'turn on by default upstream'.
Comment 4 Jonathan Earl Brassow 2014-07-14 23:40:33 UTC 
Requirements to turn on by default upstream:
- All commands must either function correctly or give a controlled error

Requirements to remove from tech preview in RHEL:
* on by default upstream
- ability to check and repair Cache LVs (i.e. their metadata LV)
- ability for cache to work on RAID LVs

Other features needed at some point:
- resize Cache data LV (w/o removing and recreating cache LV)
- resize Cache metadata LV (w/o removing and recreating cache LV)
- ability to change cache policy (w/o removing and recreating cache LV)
- ability to change cache mode (w/o removing and recreating cache LV)
- cache profiles
Comment 5 Jonathan Earl Brassow 2014-07-15 00:17:08 UTC 
Need to check if the following bugs still exist upstream where they could cause a problem for RHEL7 like they have in rhel6:
- Bug 1107345:  Cache regression.
- Bug 1104381:  Cache regression.
- Bug 1110026:  Cache regression.
Comment 6 Jonathan Earl Brassow 2014-07-15 00:30:57 UTC 
[other feature] Ability to create cache LV on top of a cache LV (bug 727072)
Comment 7 Jonathan Earl Brassow 2014-09-18 19:23:01 UTC 
Support for LVM cache LVs will be offered in phases:
Phase 1 includes:
- Ability to create, remove, report on Cache LVs created on top of linear, stripe or RAID LVs.
- Cache LV components (data and metadata sub-LVs) can be linear, stripe or RAID.
- The user must be able to select the cache mode (either writeback or writethrough)
-- This does not mean they must be able to switch cachemode while the cache is in-use.

Phase 2 includes:
- Ability to take snapshots of cache LVs
- Ability to use cache LVs as thin sub-LVs

This bug tracks bugs associated with achieving phase 1:
Bug 1086426 [RHEL7] Problems attempting to remove cache pool before cache origin
Bug 1086442 [RHEL7] RFE: allow raid scrubbing on cache pool raid volumes

Comment 14 Petr Rockai 2014-10-07 07:11:40 UTC 
I have POSTed those 2:
Bug 1124414 [RHEL7] LVM cache: dmeventd does not work on RAID volumes that are under cache
Bug 1133093 [RHEL6] no way to split off cache pool raid images

I am also taking this one (similar to the 2 from above):
Bug 1086442 [RHEL7] RFE: allow raid scrubbing on cache pool raid volumes

while Jon has MODIFIED this one a while back:
Bug 1103381 [RHEL7] LVM cache: Not all sub-LVs renamed when caching a RAID LV

so the following still need resolving (6):
Bug 1109974 [RHEL7] need a more graceful error when attempting to cache an origin that is already cached
Bug 1111748 [RHEL7] kernel BUG at drivers/md/persistent-data/dm-btree-spine.c when taking snapshot of a cached XFS
