v12.2.8 released是一个长期支持版本。
网页的介绍如下：We’re glad to announce the next point release in the Luminous v12.2.Xstable release series. This release contains a range of bugfixes andstability improvements across all the components of ceph. We thank everyone for contributing towards this release.Upgrade notes from previous luminous releasesWhen upgrading from v12.2.5 or v12.2.6 please note that upgrade caveats from12.2.5 will apply to any _newer_ luminous version including 12.2.8. Please readthe upgrade notes on 12.2.7For the cluster that installed the broken 12.2.6 release, 12.2.7 fixed theregression and introduced a workaround option `osd distrust data digest = true`,but 12.2.7 clusters still generated health warnings like ::[ERR] 11.288 shard 207: soid11:1155c332:::rbd_data.207dce238e1f29.0000000000000527:head data_digest 0xc8997a5b != data_digest 0x2ca1585312.2.8 improves the deep scrub code to automatically repair theseinconsistencies. Once the entire cluster has been upgraded and then fully deepscrubbed, and all such inconsistencies are resolved; it will be safe to disablethe `osd distrust data digest = true` workaround option.
后面一句是重点。
提升了deep scrub 自动修复不一致。解决兼容问题，变通方法选项 osd distrust data digest = true 可选方法是安全的
