Debian User Forums

Yes I did. I said all sessions are sudo su. And yes I did, I gave you examples of the attributes. You want me to copy and paste a session screen on one machine, save it to a usb, bring it to this machine and copy and paste it in here, which will show you exactly the same characters in the exactly th...

Just to clarify a point, what I mean by Root not being the same user:
Root creates a file on node A. Root on node B can't edit the file, and the same In reverse. I've proved this to be true if the files stay in the created location or copied to a new location/node/disk.

I didn't get chance to get back to this until today. I couldn't see any problems with the mounts, certainly not read only, I could create new files on the drive from anywhere, just couldn't edit a bunch of them. I went back to the original data source just to check I wasn't going mad, but no, everyt...

Two drives. Two servers. Network copy, from a samba share.

Could you mount have anything to do with it, at copy or access time?

Hi folks. Yes, data store was kind of vague. Just a bunch of directories with files in, sh files, py files, a couple of iso, nothing special, not databases. Copying: cp. I think, but it was a while ago now, could have been synced. Permissions: They look the same with an ls -l. On the original drive ...

Hi folks. I have recently moved a data store from one server to another, different ips, different disks but same file system. I performed everything as root (same login details) on both machines. However, now I can't edit the files. I can open, but no permission to save. This suggests there is a fil...

Hi folks. I know how to send normal output to a file, and how to use tee for a copy to screen. That's all well and good. But if I have a script with many echos and commands I'm doing a lot of editing if anything changes. Is there a way to: Do Stuff. Send ALL following output to file log.log Do more ...

Hi folks. I have a backup routine which runs nightly, nothing complicated, a simple cp from one external sata drive to another, one node to another. It works fine when it works. However, these machines aren't huge servers and sometimes they go wrong. Last night, for some unknown reason, the mount to...

Does knowing my UID number make a difference to the answer?

Thanks for the info on the nofail, I'd picked that up from another site that said tack it on the end.

Hi there. I have two pis, both running Debian 9 Stretch, all up to date, both have an ssd attached via Sata. In fstab I have the line UUID="blah blah" /mountpoint etx4 defaults 0 0 nofail. Exactly the same line, with the UUID different. Of course. If I df on these two pis I get different r...

In my defence, I have 130 SDs and adapters here, i looks as if at least a couple of them aren't seating properly. As I'd used multiples of them, and the reader reads, I had discounted them (foolishly) from the equation.

Lesson learnt. (Very embarrassed face)

Arse, no, that's my fault hang on....

If I've got a dodgy card reader I'm going to be miffed...

As an example.... I get the same results if I check an Ubuntu image, a Raspbian image, Debian. root@p131:/# fsck /dev/sda fsck from util-linux 2.29.2 e2fsck 1.43.4 (31-Jan-2017) fsck.ext2: No medium found while trying to open /dev/sda The superblock could not be read or does not describe a valid ext...

Should fsck work ok with an img on an sd card in an external reader? With several images from various vendors of pis I'm getting loads of invalid superblock errors, and suggestions to try ex2 which just gives the exact same error. Surely fsck knows how to interrogate an sd with an image on it? I hav...

Sorry folks, I didn't mean to cause any offence with a second post, I felt the issues where different as I'd definitely found where the problem starts. I did look through the returns on the other thread but nothing has helped. Let me run through exactly what I'm doing, I gather I've rambled a bit a ...

While searching through the ever decreasing circles, I stumbled on TestDisk. Running this tells me the disk (sd) isn't bootable. Well it is. It also gives me 3 errors where start and end blocks don't match. Something is going every wrong at a low level. Do I need a different image to start with? As ...

Hi folks. I started a thread on this problem a while ago, but I had no idea where the issue was starting. Having re-flashed a couple of SDs recently I've found the culprit. I have a Debian stretch image which I've flashed to a couple of SDs and spun up in Banana pis. All works fine, but the image is...

Hi there. On a Debian node I have an SSD attached via Sata with a relevant entry in fstab. This all works fine. But, if the drive//cable is removed the machine halts during the boot process. It kind find the drive, therefore it stops. Is there a way to bypass this behaviour? If the drive isn't found...

Ahhh, ok.... root@p134:/home/pi# parted --list Model: KINGSTON SA400S37240G (scsi) Disk /dev/sda: 240GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags Error: /dev/mmcblk1boot0: unrecognised disk label Model: Generic SD/MMC St...
