Hi Roland, Sorry for the late reply.

Hi Hernán,

H> Hello, Tyring a new installation here from USB using the current H> installer H> https://www.qlustar.com/sites/default/files/downloads/qlustar-installer-1...

H> My server started to boot correctly, however a kernel panic H> happened. You can view kernel dump details here: H> https://imgur.com/a/7jSCHuJ

the most likely cause for this is a bad USB flash drive. You can check whether it's Ok as follows:

a) Unzip the downloaded installer image and check the sha256 sum of the uncompressed iso. Things should look like this:

$ ls -l qlustar-installer-10.1.0-0.iso -rw-r--r-- 1 you you 798732288 Nov 17 12:46 qlustar-installer-10.1.0-0.iso

$ sha256sum qlustar-installer-10.1.0-0.iso d314fea13f8e342496df078a7c66de10fe9c3d978fe0ab3629fa7afa12a8db2e qlustar-installer-10.1.0-0.iso

I did it again to burn it in a new USB drive and everything looks fine: # sha256sum.exe /d/Hernan/USB_3/qlustar-installer-10.1.0-0.iso d314fea13f8e342496df078a7c66de10fe9c3d978fe0ab3629fa7afa12a8db2e

b) Now burn this iso to your UBS drive (assuming it's /dev/sdb) as follows:

$ dd if=/tmp/qlustar-installer-10.1.0-0.iso of=/dev/sdb $ sync

This is not so easy in Windows. I wanted to burn the ISO image from MSYS2 CLI but it doesn't provide an easy way to specify a removable device like /dev/sdb using dd of. In theory it should be possible to list drives with: wmic diskdrive list brief /format:list and then perform something like: gunzip -c qlustar-installer.iso.gz | dd of=//./PhysicalDrive1 However didn't worked. I ended up using Rufus https://rufus.ie/en_IE.html. This Rufus only provides formatting USB drive as FAT, FAT32 and NTFS, which I guess that was the cause of problems. I finally managed to install Qlustar using a Linux box and verifying its contents as you suggested. Thank you very much for your help. Cheers, Hernán

c) Now unplug the USB drive and plug it back in (to be sure not to read back from cache in the next step). Make sure that it's block device remains the same (here /dev/sdb).

d) Now read the iso back from the USB drive and check it's sha256sum $ dd if=/dev/sdc bs=2048 \ count=$(( $(stat -c '%s' qlustar-installer-10.1.0-0.iso) / 2048 )) | \ sha256sum 390006+0 records in 390006+0 records out 798732288 bytes (799 MB, 762 MiB) copied, 5.18606 s, 154 MB/s d314fea13f8e342496df078a7c66de10fe9c3d978fe0ab3629fa7afa12a8db2e -

If the sha256sums are identical, your stick is OK, and we have to continue looking at other possible causes.

Best,

Roland
