Dear Experts,
currently I observe a strange behavior on one of our AEM 6.2 (all updates installed) publish instances. Every time I run oak-run compact, repository gets bigger, instead of smaller. There are no errors and some tar files are really removed and added like here:
size 115.7 GB (115699274801 bytes) removed files [data01280a.tar, data01429a.tar, data01389a.tar, data01564a.tar, data01393a.tar, data01235a.tar, data01410a.tar, data01456a.tar, data01293a.tar, data01375a.tar, data01579a.tar, data01574a.tar, data01326a.tar, data01289a.tar, data01547a.tar, data01385a.tar, data00312h.tar, data01445a.tar, data01327a.tar, data01588a.tar, data01577a.tar, data01332a.tar, data01485a.tar, data01217b.tar, data01495a.tar, data01339a.tar, data01420a.tar] added files [data01332b.tar, .nfsE86D61, data01485b.tar, .nfs496D61, .nfsA76D61, data01547b.tar, data01375b.tar, .nfs986D61, data01393b.tar, data01327b.tar, .nfs296D61, data01579b.tar, .nfs186D61, data01385b.tar, data01389b.tar, data01326b.tar, .nfsB76D61, data01445b.tar, data01339b.tar, data01293b.tar, data01588b.tar, .nfs686D61, .nfs586D61, data01217c.tar, data01410b.tar, .nfsC76D61, data01574b.tar, .nfs786D61, .nfsE76D61, .nfs386D61, data01495b.tar, data01456b.tar, data01280b.tar, data01577b.tar, .nfs286D61, data01564b.tar, .nfs096D61, .nfsC86D61, .nfsF76D61, .nfs086D61, .nfs486D61, .nfsA86D61, data01289b.tar, .nfs396D61, data00312i.tar, .nfsF86D61, data01429b.tar, .nfsD86D61, .nfsD76D61, .nfs886D61, .nfsB86D61, .nfs196D61, data01420b.tar, data01235b.tar] Compaction succeeded in 8.109 min (486s).
But each time the "compaction" adds about 3GB of extra volume. On other publishers the repository size after compaction is about 10GB, so I am already 10 times over normal size
What can be done to remediate this issue?
Kind regards,
Ivan

Sorry, found the reason.
Oak is running on NFS. After compaction some .nfs files stay behind. In the example log above: .nfsE86D61...
These can be removed safely after oak-run exits.
Kind regards,
Ivan

Hi,
Running on NFS (especially the .tar files) will definitly have an performance impact, as the system cannot use memory mapped files (mmap) to speedup the repository access.
