Environment

• Windows version: Windows Server 2022 Standard
• Processor architecture: 64bit
• Dokany version: Reproducible in latest version
• Library type (Dokany/FUSE): Dokany

Check List

• I checked my issue doesn't exist yet
• My issue is valid with mirror default sample and not specific to my user-mode driver implementation
• I can always reproduce the issue with the provided description below.
• I have updated Dokany to the latest version and have reboot my computer after.
• I tested one of the last snapshot from appveyor CI

Description

I have an application that uses Dokan to mount a store located on a SAN drive. Occasionally, the mounted drive intermittently switches to a local drive. Although the issue can be reproduced using the mirror.exe tool, it does not occur consistently.

Steps to reproduce:
1.Mount a network drive.
2.Continuously refresh the File Explorer. Occasionally, the mounted drive will switch to a local drive if the load on network drive is high. (Another way to reproduce is by disconnecting the network drive after mounting)

Hi @dheeraj1729 ,

The drive cannot switch to local drive but I think what you see is that the request to get the volume information is slow and during that time the drive looks like that. I would suggest adding caching where possible to quickly complete the dokan requests.
Mirror does not have cache as it is a sample to learn how Dokan works.
