[LU-264] MMP update

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Affects Version/s: Lustre 1.8.6
• Severity: 3
• Assignee: Niu Yawei (Inactive)
• Reporter: Johann Lombardi (Inactive)

Description

I made some changes to MMP to push it upstream:
http://thread.gmane.org/gmane.comp.file-systems.ext4/24675

e2fsprogs patch:

• use blk64_t instead of blk_t
• bump update interval to 5s

kernel patch:

• add more comments to struct mmp_struct
• remove unused EXT4_MMP_UPDATE_INTERVAL
• change check interval multiplier from 5 to 2
• use ext4_fsblk_t instead of unsigned long for the MMP block

We should integrate those modifications into our own kernel & e2fsprogs patches.

Here is the initial thread for reference:
http://thread.gmane.org/gmane.comp.file-systems.ext4/24301/focus=24306

Issue Links

• is duplicated by: LU-268 Possible bug in userspace block handling when enabling MPP
• Trackbacks: Lustre 1.8.x known issues tracker While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA
