* [pbs-devel] [PATCH proxmox-backup v2 0/3] fix #3786: resync corrupt chunks in sync-job @ 2024-10-18 9:09 Gabriel Goller 2024-10-18 9:09 ` [pbs-devel] [PATCH proxmox-backup v2 1/3] fix #3786: api: add resync-corrupt option to sync jobs Gabriel Goller ` (2 more replies) 0 siblings, 3 replies; 8+ messages in thread From: Gabriel Goller @ 2024-10-18 9:09 UTC (permalink / raw) To: pbs-devel Add an option `resync-corrupt` that resyncs corrupt snapshots when running sync-job. This option checks if the local snapshot failed the last verification and if it did, overwrites the local snapshot with the remote one. This is quite useful, as we currently don't have an option to "fix" broken chunks/snapshots in any way, even if a healthy version is on another (e.g. offsite) instance. Important things to note are also: this has a slight performance penalty, as all the manifests have to be looked through, and a verification job has to be run beforehand, otherwise we do not know if the snapshot is healthy. Note: This series was originally written by Shannon! I just picked it up, rebased, and fixed the obvious comments on the last series. Changelog v2 (thanks @Thomas): - order git trailers - adjusted schema description to include broken indexes - change verify_state to return a Result<_,_> - print error if verify_state is not able to read the state - update docs on pull_snapshot function - simplify logic by combining flags - move log line out of loop to only print once that we resync the snapshot Changelog since RFC (Shannon's work): - rename option from deep-sync to resync-corrupt - rebase on latest master (and change implementation details, as a lot has changed around sync-jobs) proxmox-backup: Gabriel Goller (3): fix #3786: api: add resync-corrupt option to sync jobs fix #3786: ui/cli: add resync-corrupt option on sync-jobs fix #3786: docs: add resync-corrupt option to sync-job docs/managing-remotes.rst | 6 ++++ pbs-api-types/src/jobs.rs | 10 ++++++ pbs-datastore/src/backup_info.rs | 13 +++++++- src/api2/config/sync.rs | 4 +++ src/api2/pull.rs | 9 +++++- src/bin/proxmox-backup-manager.rs | 13 ++++++-- src/server/pull.rs | 52 ++++++++++++++++++++++++++----- www/window/SyncJobEdit.js | 11 +++++++ 8 files changed, 106 insertions(+), 12 deletions(-) Summary over all repositories: 8 files changed, 106 insertions(+), 12 deletions(-) -- Generated by git-murpp 0.7.1 _______________________________________________ pbs-devel mailing list pbs-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel ^ permalink raw reply [flat|nested] 8+ messages in thread

When traversing the remote snapshots, we check if it exists locally, and if it is, we check if the last verification of it failed. If the local snapshot is broken and the `resync-corrupt` option is turned on, we pull in the remote snapshot, overwriting the local one. This is very useful and has been requested a lot, as there is currently no way to "fix" corrupt chunks/snapshots even if the user has a healthy version of it on their offsite instance.

You're right the BackupManifest is loaded here twice actually. So I could move this function to a getter in BackupManifest and then move the construction of it (src/server/pull.rs:396): let manifest = BackupManifest::try_from(tmp_manifest_blob)?; up to (src/server/pull.rs:365). And instead of having the try_block to try read from the manifest just call BackupManifest::try_from.

That's true, that would be cleaner. The downside is that we would have open/parse the BackupManifest twice. I could write something like: if params.resync_corrupt { let local_dir = params.target.store.backup_dir(target_ns.clone(), dir.clone()); if let Ok(dir) = local_dir { let verify_state = dir.verify_state(); if verify_state == Some(VerifyState::Failed) { return true; } } } >because right now, this will not only resync existing corrupt snapshots, >but also ones that have been pruned locally, but not on the source >(i.e., the other proposed "fixing" sync mode that syncs "missing" >old snapshots, not just corrupt ones).

I think we do want both of these, but they are not a single feature, since the "sync missing snapshots" option would effectively undo any pruning you do on the target side. Their implementation is of course somewhat intertwined, as they both affect the snapshot selection logic. They might even be both enabled and combined with remove_vanished to have a sort of 1:1 repairing replication going on (with all the pros and cons/danger that comes with it). For syncing missing snapshots we might also want to require additional privileges to prevent lesser privileged users from stuffing backup groups (i.e, at least require Prune privs?). _______________________________________________ pbs-devel mailing list pbs-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel ^ permalink raw reply [flat|nested] 8+ messages in thread

It is listed in the `Advanced` section, because it slows the sync-job down and is useless if no verification job was run beforehand.
