In order to protect the flashdrive from wearing out with rewrites, the distro needs to be persistent, but write its persistent file to the flashdrive only when shutting down. Adjust the disk size in the box at the top of the window. Specify a name for the disk, configure the disks properties, and select Blank as the Source type. Under Additional disks, click Add new disk. On the VM instance details page, click Edit. This application is able to create persistent live drives that work in both UEFI (MBR or GPT) and BIOS mode, with casper-rw being used for the persistent storage partition, so it can have a size of. Double-click on the desktop icon labeled RamDisk Configuration. Check the box and click the name of the instance where you want to add a disk. It can be used to create not only bootable Windows drives from ISO files or disk images, but also create bootable Linux USB drives from Windows.
Create a DAX volume by using Windows PowerShellīecause DAX is a property of the file system, it must be specified when formatting an NTFS volume.Īfter creating a volume, use the -IsDax switch with the Format-Volume cmdlet to format the volume to be DAX-enabled. I need to install Linux to boot from a 4GB USB, and run from RAM. Be sure to include all the components during the installation. If you want to use large and huge memory pages for your memory mapped sections, do not turn on BTT.
BTT mitigates this risk by providing atomic sector update semantics for persistent memory devices, essentially enabling block-like sector writes so that apps can avoid mixing old and new data in a failure scenario.Īlthough we recommend enabling BTT on most DAX volumes to avoid subjecting the NTFS metadata to torn write issues, the downside of BTT is that it can impact the usage of "large" and "huge" memory pages on a DAX volume because remappings will occur for metadata operations. on Settings/Server is ssh What I tried as a test was to make a VM with windows.
I think I now have my answer on the filesystems: its not possible to make /rambin read-write, scroll down to the last command. Volatile RAM disks whose content disappears on shutdown. Persistent RAM disks with associated on-disk images. Up to approximately 3.5 GB on 32-bit systems. I am able to modify /etc/fstab, but the changes I make arent persistent. In practice, up to 26 disks due to the number of drive letters available. Its some other filesystems mounted on various folders that are read-only. We strongly recommend that you use DAX in conjunction with the block translation table (BTT) to protect against "torn writes" that can occur in the case of a power failure or system outage. Also the root filesystem seems to be read-write already.
If you don't use DAX correctly, there is potential for data loss. DAX isn't supported on Azure Stack HCI environments.
