Re: MDSs still core dumping

[Sergey Malinin <hell@xxxxxxxxxxx>]

I was able to start MDS 13.2.1 when I had imported journal, ran recover_dentries, reset journal, reset session table, and did ceph fs reset.

However, I got about 1000 errors in log like bad backtrace, loaded dup inode, etc. and it eventually failed on assert(stray_in->inode.nlink >= 1) right after becoming 'active'.

I'm doing scan_links to give it another try.

I need the data, even if it's read only.

After full data scan you should have been able to boot mds 13.2.2 and mount the fs.

The problem started with the upgrade to 13.2.2. I downgraded to 13.2.1 and Yan Zhen told.

mds reports problems with the journals, and even reseting the journals MDS wont start.
