I have run: e2fsck -n -v —-mdsdb /tmp/mdsdb /dev/mapper/mpath1p1 >> /tmp/mdsdb_results2.txt On my MDS as it is crashing regularly and it says I have unattached inodes which means presumably I just have to run lfsck -l -v after I have run the e2fsck on the OSTs against the MDSDB to put them into lost+found. I couldn’t do this before because when this corruption originally happened it wouldn’t let me run e2fsck on one of the OSS’s because it had external journals but I discovered (in part by what Andreas said on Friday) that I can remove the journal and then recreate it internally thereby allowing me to run e2fsck and therefore lfsck correctly. So my question is, this is just a corruption in the MDS - i.e. metadata not the OSTs so does that mean I won’t lose any actual data files, just file references? What data loss should I expect? Let me know. Thanks!
