Do NOT use #ReFS!
2 days ago I've updated to #Windows11 24h2 from Windows 10.
I have a drive for all my projects with ReFS #filesystem on it.
After an update my ReFS drive is not recognized by Windows. System says that partition is damaged and have to be reformated.
After hours of googling and reading forums I found info about that #Microsoft just silently dropped the old ReFS driver and replaced it with a new one which is not compatible with older partitions.
Windows Server 2022 at the same time does a silent upgrade of your volume without any problems.
If you are in the same situation, you have two options:
1. Boot from Windows10 live image and rescue your data;
2. Get a Windows Server VM, attach the whole physical disk with ReFS partition to it, boot and wait about 5 minutes (or try opening your refs volume inside the VM).
@cyrmax They just love these ReFS surprises :)
Some time ago they released an update for Windows Server which made all ReFS partitions inaccessible. It was kind of fun when some of our mail servers went down because of it as they lost their data partitions on the next reboot.
@shuro
Btw tell me please why Windows server and not linux?
I mean yes, some companies need windows server because of maybe some internal network shares or something else.
But for what an usual user or system administrator would choose winserver instead of linux?
@cyrmax It works well with Microsoft Outlook :)
All these things like meeting scheduling, sending on behalf, shared mailboxes and calendars with different access rights, automatic SMIME, message recall, deep integration with Active Directory and other things, dynamic distribution groups, etc...etc...
Also clustering support with failover, handling tens of thousands of mailboxes totalling tens of terabytes of active data, exports, backups, retention...
Sure you can build something similar for most things out of open source but at scale things start getting out of hand quickly unless you have entire team supporting it.
However the next Exchange seems to be subscription based so I guess the change is imminent.
