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
Bug 1124414 [RHEL7] LVM cache: dmeventd does not work on RAID volumes that are under cache
Bug 1135639 [F  20] lvconvert ignores '--cachemode writethrough' for cache pools
Bug 1110965 [RHEL7] need a more graceful way to fail when attempting to cache RO devices
Bug 1111671 [RHEL7] need a more graceful way to fail when attempting to remove cache pool during I/O
Bug 727072  [RHEL7] [FJ 7.1 feat] multilevel caching / tiering using SSDs
Bug 1091543 [RHEL7] bogus error when attempting to split images from raid1 cache origin volume
Bug 1091553 [RHEL7] "Internal error: Performing unsafe table load" error during snapshot of cache origin volume removal
Bug 1102949 [RHEL7] RFE: allow pvs in cache volumes to be vgsplit off
Bug 1104821 [RHEL7] Buffer I/O errors when configuring cache 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
