Deduplication + Team Foundation DropFolder

-

hi everyone,

we got , issue using windows server 8 + deduplication feature + dfs replication. dfs share used drop folder team foundation build server. drop folder used ~200-300 build definitions read/write data to/from drop folder. once switched windows server 2008 r2 dfs share (disabled target) windows server 8 dfs share (enabled target) - started getting crc issues builds "read" drop folder of previous build. actions copy drop folder , copy drop folder executed same build machine... if try copy same drop folder once again - no crc errors appears (to local machine or build agent), if open "working folder" of build definition - find files broken , md5 hash differs actual. (it noticed on zip files, not verified dll/exe , etc)

eventlog not report issues, replication configured "night", issue reproducing rate high if build template #2 executed "right after" build template #1 completed (copied files drop folder), not 100% reproducing rate, issue started appearing on "second day" of using windows server 8 fileshare dropfolder, issue noticed ~10 times / ~50-100 builds.

of course reverted windows server 2008 r2 share, , issue stopped reproduce

environment description..

servers:

1) windows server 2008 r2 (fileshare role) -> \\win2k8\builds (size ~350-400gb of zip/dll/sql/exe files)

2) windows server 8 (fileshare role, esx virtual machine, located on iscsi storage qnap-879 3x3tb raid5) -> \\win8\builds (volume cache-write -> on, d:\builds enabled nightly deduplication job, after synchronize ~100-150gb, dedupstatus -> savingrate 74%, savingspace 386gb, optimizedfiles 666356, inpolicyfiles 598357)

3) windows server 2008 r2 (tfs 2010 build agent machine)

build templates (tfs 2010 build) :

1) building code template (template code source control, compile, run tests, copy drop folder)
2) promote, configure , deploy template (template get's "last" successful build "building code template", patch series of xml , execute deployment staging environment)

please advise?
