Cold VHDs missing from Data Deduplicated storage volume

-

this has happened twice now. seems though whenever deduplication garbage collection runs on our server 2012 r2 hyper-v host, vhds cold (not turned on) vms disappear.

the vms still visible in hyper-v manager, disks gone off storage volume.

does have idea why might happening?

hi,

thank posting question. indeed interesting. there no limitations deduplicating volumes turned off vm’s vhd/vhdx files. live file support dedup limited vdi. if somehow caused dedup alone still understand form of corruption, files disappearing strange. 1 turn on audit on files; rather suspect interfering driver able interact on io stack. installed antivirus software backup solution, encryption software or driver loaded.

thanks,
basar
