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...

Thanks - now we are getting somewhere. I do appreciate all the posts , but it pretty much covered what I know about "grub". I'll czech the /boot/efi/EFI. and report back.

Sorry abiut this blank entry - my internet connection went kaput .

I do not have access to Ubuntu forum so I am posting my question here. My system is mutiboot , all Ubuntu. When I boot I get text screen with menu entries with access to my OS's I assume it is build by ":grub". However , the first entry( on top) is "ubuntu" - single line text, not a OS...

See the silly title Thanks

qy@qy-desktop:~$ sudo mdadm --detail /dev/md127 >>/etc/mdadm/mdadm.conf bash: /etc/mdadm/mdadm.conf: Permission denied qy@qy-desktop:~$ Please help me to gain access to mdadm,conf

OK , I have created mount point and attempt to mount the new md25 array. I have buidl the array copying existing , wiht data, partiton. "--created " reported a file system xyz. Now I get "no valid NTFS " - I do not wnat NTFS - that is windoze I neex ext4 and DO NOT WANT to loose the data...

qy@qy-desktop:~$ sudo mdadm --detail --scan > /etc/mdadm.conf bash: /etc/mdadm.conf: Permission denied qy@qy-desktop:~$ mdadm --detail --scan > /etc/mdadm.conf besides - I have /etc/mdadm/mdadm.conf and get same permission denied

Yes it does - confirming that fstab is read on boot... Now what the heck we need mdadm.conf ? Unfortunately my loss is of md varitety - lsblk is only telling me I have RAID /dev and no md number / name.... so I cannot look at md since I have none - except in mdadm,conf . Just noticed...

Thanks , however , I have used that link already. Unless I missed it , it does not answer my questions. What I really need is to find a way to recover inaccessible array. It cannot be simply "--create" beause the old devices are "busy" . Ideally if I can find out to what "md" the old...

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...

I actually found that stopping the old array unbusy the device to be added to new array. Made a typo and added the old device to wrong md45 . ended up with 1 device array and no way to access md45. So I have a real RAID 5 to add the old device too....It all takes its sweet time. But I am...

Here is the "add" result qy@qy-desktop:~$ sudo mdadm --assemble /dev/md35 --update=uuid --uuid=b1db014e:d6652122:03547a11:d943e0f0 /dev/sdf24 [sudo] password for qy: mdadm: /dev/sdf24 is busy - skipping So it is back to How to unbusy a device BUT the old array is resynching , maybe I...

I am in the process adapting the procedure. This ID is for the old array, I thing i need ID of one of the old devices being added to new array. But that is all taking time...

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 started identical process, and have posted request for help elsewhere. I am having a problem with "device busy..." and as soon as that is solved I will try what your article is suggesting. Appreciate your help very much,
