[lustre-discuss] EC branch not working with actually “killing” targets

[Patrick Farrell]

Stepan,

You'll have to give a bit more detail about how it fails, sorry!  Happy to have you interested.

Subject: [lustre-discuss] EC branch not working with actually “killing” targets

Hey everyone!

New update about EC branch.

I tested different server shutdown’s, and found a case. If I umount OST on OSS or just kill whole OSS(reboot server), filesystem falls and stop working at all.
In case of 24 OST’s and -c 16 okay, I know the reason why the system falls. But with —ec—expert mirror resync funtion dies too(lags into core).

Thoughts ?


Thanks,

Stepan
