If yes, can you provide a description beyond the summary line of what needs to be implemented.</p> <p>The quota master maintains multiple different local quota files (IAM files for ldiskfs):</p> <ul class="alternate" type="square"> <li>a global quota file with the global limits as well as how much space is globally allocated to all slaves</li> <li>one quota file per slave storing how much space is allocated to this slave</li> </ul> <p>For quota allocation/release, the global quota file and the slave one are updated transactionally so they <b>should</b> never be inconsistent in theory. However, in case of corruption, it would be great to have a mechanism to verify that, for each uid/gid, sum(slave_space) = global_space and to fix it if it is inconsistent.</p> Development Epic/Theme Project Rank 1|hzuvrb: Rank (Obsolete) 2807
