I have posted a request for help and got nowhere I am still having same annoying issue which I would like to resolve with help of somebody . Is that feasible ?

I have made an error and located all my C++ development in same partition where my OS is located . I like to duplicate/ cone /copy the entire partition and be able to continue to work on my C++ code. I understand that "dd" could do that. How about "gparted " ? Or any other application ? I would...

I am posting a new thread about general RAID. (if it is OK with management ) I like to keep the discussion on target I like to post a question and have forum to discuss / answer it. ( Side trips are OK but keep on subjects. ) 1. After array is "--create" How is it mounted ? mkdir...

1. What is the mdadm command to dynamically monitor array resync ? --detail gives "one shot " look at the process 2. when "spare rebuilding " newly added spare, does it really updates with data if it is "spare" and has not been added / grow the # of devices?

I have totally lost access to my software RAID5. I can see the RAID 5 devices , HDD partitions, but file manager won't let me access them. Is there some other way to recover the contents of the RAID5 device ? I am currently rebuilding a new RAID5 and I have added one of the failed devices to...

I needed to add another device - its data - to my working RAID5 To do so I had to unmount the device. Worked as expected. Here is the current state of the array: qy@qy-desktop:~$ sudo mdadm --detail /dev/md10 /dev/md10: Version : 1.2 Creation Time : Sun Dec 19 13:28:26 2021...

Ubuntu "file manger" shows "SDF_RAID" , the "tool tips " shows "SDF_RAID2" . I like to add this folder as "dev" to my RAID array. Is there a command I can use to "convert " which ever designation is correct to physical device ? I can fiddlke wiht "disks" or "gparted" - but Is there a...

In my interpretation - there are (minimum 3 ) real hardware devices in RAID5 array. Then there is "md" software device keeping it all organized / in synch. "file manager" lets me access all of these hardware devices - with some effort . "md" is not manually writable. However - since "md" keeps...

My best guess is hardware failure - limited to first disk partition... suggested remedy to run fsck manually keeps repeating , hence no fix I have copied the misbehaving partition, run "update grub" and BOTH of them works as expected. My best guess - my 3TB HDD is flaky

In multiboot system, all Linux ubuntu , on startup , some file's icons display on "desktop" and some on the "sidebar". What setup / options controls that ?

On my multiboot system, all Linux, only last OS addition (21.10) gives "progress report " during boot. It has been working since first install - by optioning " GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" " in grub. It is a handy feature to see boot process / progress. My default boot is UEFI /...
