• Severity: 3

Description

The test steps is:
1.on lustre-2.1.4, set quota limit for quota_2usr and run IOZONE to use up the limit
2.stop lustre, upgrade the whole system to 2.4, enable quota on the new system
3.run IOZONE again on lustre-2.4 with the same user, should expect EDQUOT but the user can still write data exceed quota limit a lot.

Sarah, did you enable quota on the MGS via lctl conf_param? If not, enforcement won't be enabled and this behavior is expected.

[Niu Yawei (Inactive)]

Seems there is a defect: after the global index & global index copy were created, they both set the initial version as 1, so even if the global index migration happened, slave will not reintegrate the global index...

I did lctl conf_param lustre.quota.mdt/ost=ug
