(Updated March 22, 2016, 11:24 p.m.) Review request for mesos, Jie Yu and Jiang Yan Xu. Changes ------- Rebased. Bugs: MESOs-4828 https://issues.apache.org/jira/browse/MESOs-4828 Repository: mesos Description ------- Track sandbox directory usage by dynamically assigning XFS project quotas. We track a range of XFS project IDs, assigning a project ID and a project quota to each sandbox as it is created. When the task reaches the quota, writes will fail with EDQUOT, and the task will have an opportunity to handle that. Quotas are not applied to volume resources since the isolator interface has no insight into the volume lifecycle. Thus it is not currently possible to accurately assign and reclaim project IDs. If LOW is the lower bound of the project ID range and HIGH is the upper bound, you can show the currently allocated project quotas using the xfs_quota command: $ xfs_quota -x -c "report -a -n -L LOW -U HIGH" To show the project ID assigned to the file PATH, use the xfs_io command: $ xfs_io -r -c stat PATH Diffs (updated) ----- src/Makefile.am 6552e48eab2708a28dd69adba3ec759cb5aeca4c src/slave/containerizer/mesos/containerizer.cpp ee7a265975323ca891114a286357c8e42901560c src/slave/containerizer/mesos/isolators/disk/xfs.hpp PRE-CREATION src/slave/containerizer/mesos/isolators/disk/xfs.cpp PRE-CREATION src/slave/flags.hpp 3067c128f1fded4f130f4d45f191584c2f30ad9c src/slave/flags.cpp ce028825ad99f54a231b4b18dde277b63aa0525c Diff: https://reviews.apache.org/r/44948/diff/ Testing ------- Make check.
