| Description |
|
The high volume of log messages generated by the existing 2.8 accounting code in osd-zfs: failed to remove [0x6c0000404:0x6a038f:0x0] from accounting ZAP for grp XXXXX is obscuring real problems. |

Please backport the following to allow Lustre 2.8 to use ZFS' native object accounting: The messages could just be changed from CERROR to CDEBUG, but the patches are small. |

To quantify this, we see 500-1000 such messages per month on the servers. |

I've pushed the patch to https://review.whamcloud.com/29596 Another patch is probably needed: https://review.whamcloud.com/28345, if you're going to iterate quote info from OI object. However, I don't think you should need patch https://review.whamcloud.com/28924. Less patch means less problem. Please let me know if you want any or both of them. |

Hi Jinshan, thank you. I would like all three patches. Re: 28924, I want to preserve the ability of the other sites to upgrade to ZFS 0.7.0 and then roll back if they find they need to, even though that is unlikely. |
