Consequence: Upgrading to RHELAH 7.3 from RHELAH 7.2.7 may not use static deltas
Workaround (if any): If the system contains the refspec 'rhel-atomic-host:rhel-atomic-host/7/x86_64/standard' in the output of 'ostree refs', the user should delete the refspec with the command 'ostree refs --delete rhel-atomic-host:rhel-atomic-host/7/x86_64/standard' and perform the upgrade.
Result: Using 'atomic host upgrade' to upgrade 7.3 should retrieve static deltas. The output from the command should look similar to:
# atomic host upgrade
Updating from: rhel-atomic-host-ostree:rhel-atomic-host/7/x86_64/standard
21 delta parts, 15 loose fetched; 214444 KiB transferred in 73 seconds

Yeah, something is clearly going badly wrong here. I get in the end: 21 delta parts, 6231 loose fetched; 405931 KiB transferred in 381 seconds Why did we fetch over 6000 loose objects? After debugging with @walters a bit this morning, it looks like this is a side effect of BZ#1233358 After registering with subscription-manager, we end up with two refspecs that use the same branch, but on different remotes: # ostree refs ostree/1/1/0 ostree/1/1/1 rhel-atomic-host-ostree:rhel-atomic-host/7/x86_64/standard rhel-atomic-host:rhel-atomic-host/7/x86_64/standard When the client goes looking for deltas, it incorrectly tries to find a delta for the commit associated with the refspec 'rhel-atomic-host:rhel-atomic-host/7/x86_64/standard'. This can be teased out with the 'ostree pull --require-static-deltas' command. # rpm-ostree status State: idle Deployments: ● rhel-atomic-host-ostree:rhel-atomic-host/7/x86_64/standard Version: 7.2.7 (2016-09-09 18:43:35) Commit: 347c3f5eb641e69fc602878c646cf42c4bcd5d9f36847a1f24ff8f3ec80f17b1 OSName: rhel-atomic-host rhel-atomic-host-ostree:rhel-atomic-host/7/x86_64/standard Version: 7.2.6-1 (2016-08-18 16:01:03) Commit: dae35767902aad07b087d359be20f234d244da79fdd4734cd2fbc3ee39b12cf8 OSName: rhel-atomic-host # env OSTREE_DEBUG_HTTP=1 ostree pull --require-static-deltas rhel-atomic-host-ostree rhel-atomic-host/7/x86_64/standard ... error: Static deltas required, but none found for dae35767902aad07b087d359be20f234d244da79fdd4734cd2fbc3ee39b12cf8 to 90c9735becfff1c55c8586ae0f2c904bc0928f042cd4d016e9e0e2edd16e5e97 To work around this, we can delete the "old" refspec and then try to perform the upgrade again. And then we will see the deltas being fetched. # ostree refs --delete rhel-atomic-host:rhel-atomic-host/7/x86_64/standard # rpm-ostree upgrade Updating from: rhel-atomic-host-ostree:rhel-atomic-host/7/x86_64/standard 21 delta parts, 15 loose fetched; 214444 KiB transferred in 73 seconds We have doc text explaining a workaround and this issue does not exist in the current release, so I am closing this. |
