Hello, all I hava a Ceph cluster of Hammer 0.94.5, 3 Hosts and the cluster is 3 MONs and 8 OSDs for each host.
When test the date recover and backfill of EC pool (K=2, M=1), each chunk for one host, I have an issue of the PG state. When the Ceph cluster state change activate+clean
by “ceph -s”, I reboot one host of the cluster, some PGs will go down and find some data’s chunk is missing. From the PG map, I find the 3 PGs(1 pg_temp and 2 pgs) only map to two hosts. Does anyone know the pg_temp is still exist when the cluster state changes to activate+clean? And explain when and how does the pg_temp disappear? 本邮件及其附件含有杭州华三通信技术有限公司的保密信息，仅限于发送给上面地址中列出 的个人或群组。禁止任何其他人以任何形式使用（包括但不限于全部或部分地泄露、复制、 或散发）本邮件中的信息。如果您错收了本邮件，请您立即电话或邮件通知发件人并删除本 邮件！ This e-mail and its attachments contain confidential information from H3C, which is intended only for the person or entity whose address is listed above.
