I am running Hassio on a Raspberry pi 3B.
Now I want to move from sd-card to ssd
I want to keep as much settings as possible, now i wonder what is the best method :
Install new version and restore snaphot
make image of sd card and put it on ssd with etcher (ssd = larger than sd)
Fresh install and copy config- folder from backup
I could try every method myself, but because copying takes lots of time I would like to hear from others who did this before.
I tried 1) once. The full snapshot didnāt restore all the files and I had to keep restoring the snapshot to get it partially working. Not everything was working so I moved to 2)
I had two same size SD cards, but made by different manufacturers. I wasnāt able to re-image the card and eventually moved to 3)
Basically I did a full install from scratch and used my old config files. Still had to re-authorize a few components but it worked, just took several hours to complete.
Thank you for your answers. I try a fresh install.
I wrote most recent image to the ssd, but first install fails. Error says :retry count exceeded;starting again and after that nothing happens.
Reason can be a bad ssd, but i will try to install an older version first.
I use a ssd for several weeks now with hass.io
Works fine for me.
When copying image file with Etcher you have you have to check āUnsafe modeā in settings.
At first I did not do that resulting in errors at first boot on my RPI
Is there anything else to it? Do you just plug an SSD with USB into one of the USB ports on the Raspberry Pi and your off to the races? Said another way, is there any kind of setup or configuration required to tell the raspberry pi to use the SSD?
My SD card died a week ago. rPi stopped booting.
I bought a new SD card and tried to reinstall everything, but realized that it is too hard.
The old SD card was not readable from the PC. But it was from rPi. It just was in a read-only mode. This is how they die.
I created a backup and restored it on 128Gb SSD. Then ran sudo fsck -v -p /dev/sda1 and it found and reset the dirty bit on the sda1 partition. sda2 partition was fine.
Then it booted from SSD without a problem. HA UI works much faster. History and Logbook load in less than one second. Home, map and cameras appear immediately.
Write speed:
$ dd if=/dev/zero of=/tmp/test1.img bs=300M count=1 oflag=dsync
1+0 records in
1+0 records out
314572800 bytes (315 MB, 300 MiB) copied, 9.20859 s, 34.2 MB/s
Latency:
$ dd if=/dev/zero of=/tmp/test2.img bs=512 count=1000 oflag=dsync
1000+0 records in
1000+0 records out
512000 bytes (512 kB, 500 KiB) copied, 2.48363 s, 206 kB/s
So, if your SD card died and you do not have a backup, you may still be able to restore your installation.
I would recommend to switch to a cheap SSD.
Hi, could you let me know how you restored backup to ssd?
IĖve tried connect my ssd to rpi usb slot but rpi did not find it
Shall I do any additional settings?
Honestly the best way (not the fastest) is to do a fresh install and copy the files that you need back 1 by 1 and add all the components, sensors etc back from scratch. Because HA gets updated very very frequently there is a lot of unused files that remain etc (or corrupt files etc). I have had many problems fixed just because of a fresh install.
I know it is not the fastest, but you asked for the best way. I sincerely believe that this is the best way. As is with computers and phones. Installing Windows from scratch is always better than to restore a backup.
But then again it is totally up to you. If I were you Iād take a friday or saturday and work through this. I have a pretty large setup and it takes me about 2 evenings to get a fresh install going. This will take considerably less time on smaller setups.
Flash Hassbian on a new ssd using Etcher and boot rPI from it.
Mount your SSD and old SD card on rPI. Use an External Hard Drive Enclosure and a USB card reader, these commands are useful:
dmesg - system log about drives, you need to find your flash drive.
lsusb
sudo lsblk -o UUID,NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL,MODEL
sudo blkid
E.g. sda1 is your SSD.
sudo mkdir /mnt/bak
sudo mount /dev/sda1 /mnt/bak
ls /mnt/PIHDD
Create the backup. Be careful with disksā and partitionsā names! Yours may be different, and I may have a mistake here.
E.g. mmcblk0 is your old SD card
I have done some more research and it seems on my pi3b+ this should work as expected. My understanding is that setting the boot bit is only necessary on the non-"+" models. Flashing a bootable image with etcher should just work like an sdā¦ i hope.
Iām about to pull the trigger on a startech usb3-sata3 adapter and a kingston 120gb ssd for this. Any advice/pointers are welcome.
With hassos, hasbian, or other? From what Iāve been reading, it seems this may not actually work for me as Iām running hassos. Iāve seen there is a usb boot compatible image of hassos here, and that may be the closest method to what I was after thus far:
Iām still unclear on the differences between running raspbian+hassio as outlined in this thread:
ā¦versus just using that usb bootable image instead. Either way, I have to learn how to transfer my configuration to the new system.
I do not think it matters whether you have HASSIO or Hassbian. You just need to boot from something to run my steps. You also can use a different method to create a backup, e.g. on a PC. But anyway you need to fix a file system corruption on the restored image.
mgluk, I may well not understand it correctly. I have read a lot of info about how hassos cannot be made usb bootableā¦ devs only intend to allow moving the database to ssdā¦ etc. All the tutās on installing hassio on ssd seem to make use of either resin-os or hassbian, then you install docker, then install hassio in docker (or something like that?). Some folks use scripts to do it, some do it manually.
Iām not sure on how that goes as Iāve never done it that way; my previous instance was just a hassio (hassos based) image for rpi flashed on an sdcardā¦ plug it in, turn it on, and lovelace pops up to guide you throughā¦ no terminal commands to install docker, hassio, etc. OS updates are done through the gui (vs having to ssh in to use apt-getā¦ or making a cron job, etc). This is the ānoobā level system Iām talking about.
Well, it works! Iāve got hassos running on my pi3b+ with no sd card:
