I like to fill used drives with zeroes before re-purposing for mdadm use. It makes the drive factory fresh and avoids these kinds of problems. This will fill /dev/sda with zeroes... dd if=/dev/zero of=/dev/sda bs=1M
First of all, I don't think there's anything wrong with using a complete drive for mdadm. In other words, your setup works now, you won't have any advantage from fiddling with it any further. From the answer you're referring to: RAID-on-partition has its uses, but when you're using the drives in a pseudo-storage-pool setup, you're sometimes better off ...
I would suggest trying the 2012 instructions from http://blogs.technet.com/b/tip_of_the_day/archive/2014/10/10/tip-of-the-day-configuring-disk-mirroring-for-windows-server-2012.aspx
99.9% of the time the reason this happens is because one or more files have been deleted, but there is a process which is still writing to the old file handle. When a program wants to perform I/O operations on a file, it asks the kernel "hey kernel, I would like to access the file /bla.txt and I want to be able to read and write to it". The kernel then ...
I can only think of two reasons: a rootkit infection; filesystem curruption. Use dd to dump your partition to a removable/network disk and mount/check it elsewhere. You may get a few inconsistencies while dumping but a great chance is they will be fixable easily.
Upgrading/Recovery When performing an upgrade or recovering the OS, it is much easier and cleaner when the operating system resides on a dedicated volume. In virtual environments, one can simply copy the data ".VHD" to a new server for restoring/upgrading the service. Volume Shadow Copy Service This functionality can only be on/off on a per volume basis. ...
In my experience, the most important point is bad blocks and scandisk: you really don't ever want to see a 10TB volume getting bad blocks and in need of a scandisk, specially in an important server, as it may take several (or many!) hours to end, while your users are first asking for their files, then blaming the IT stuff, and finally shouting at you. If ...
Take a look at this answer, and a variety of searching, but the short answer is what you are talking about is not possible on a live filesystem unless it is possible to unmount the partition you wish to resize. Since it does not seem like that is possible in this case rebooting to a rescue image is probably the best option. If rebooting to a rescue image ...
For Digital Ocean in particular, you can boot the droplet into a rescue image. For older distributions that boot from an external kernel, you can select to boot it into a rescue image yourself. For newer distributions that boot from a kernel inside the droplet, you can file a support ticket to have the rescue image mounted as an ISO. Once you are done with ...
Not using a partition is totally fine. The only struggle that can appear is, if you're exchanging a disk with a different vendor and your new disk is a few blocks smaller.
