marking as low pri since this is scaling limit of quota.conf file. The configuration file may also change when glusterd2 is used. REVIEW: https://review.gluster.org/18695 (quota: fixes issue in quota.conf when setting large number of limits) posted (#1) for review on master by sanoj-unnikrishnan REVISION POSTED: https://review.gluster.org/18695 (quota: fixes issue in quota.conf when setting large number of limits) posted (#3) for review on master by sanoj-unnikrishnan REVIEW: https://review.gluster.org/18895 (quota: fixes issue in quota.conf when setting large number of limits) posted (#1) for review on release-3.12 by sanoj-unnikrishnan COMMIT: https://review.gluster.org/18895 committed in release-3.12 by \"sanoj-unnikrishnan\" <sunnikri> with a commit message- quota: fixes issue in quota.conf when setting large number of limits Problem: It was not possible to configure more than 7712 quota limits. This was because a stack buffer of size 131072 was used to read from quota.conf file. In the new format of quota.conf file each gfid entry takes 17bytes (16byte gfid + 1 byte type). So, the buf_size was not a multiple of gfid entry size and as per code this was considered as corruption. Solution: make buf size multiple of gfid entry size Change-Id: Id036225505a47a4f6fa515a572ee7b0c958f30ed BUG: 1489043 Signed-off-by: Sanoj Unnikrishnan <sunnikri> (cherry picked from commit 2899a4f125735636fe7cd8db73c0b8a13289df9b) This bug is getting closed because a release has been made available that should address the reported issue.

Description of problem: The number of bytes specified in version 3.7 or later is incorrect. Therefore, only 7711 quota settings can be registered. How reproducible: When 7711 or more quotas are registered, the following error occurs. "quota.conf corrupted" Additional info: glusterfs/xlators/mgmt/glusterd/src/glusterd-quota.c Line 927 while ((bytes_read = sys_read (src_fd, (void *)&buf, entry_sz)) > 0) { if (bytes_read % 16 != 0) {
