Hello all, We are facing extremely slow GFS2 issues in Redhat 7 64 bit. Backend is 16 Gbps FC SAN so no issues there.

I have scoured the entire (anyways most of the) Internet and arrived at the following settings.

mmap_disable = yes This is ok mail_fsync = always Try changing to never mail_nfs_storage = yes mail_nfs_index = yes These you should not use.

mmap_disable = yes

This is twice here.

lock_method = fcntl

Did a systemctl restart dovecot and did not find any major improvement. Can you please help.

Regards Durga Prasad
