My Umbrel is running in Ubuntu installed on SDD. I would like to store blk\*\*\*\*\*.dat and rev\*\*\*\*\*.dat in another HDD, but index in SSD. I tried symbolic link (soft link) as explained below, but it didn’t work. [https://en.bitcoin.it/wiki/Splitting\_the\_data\_directory](https://en.bitcoin.it/wiki/Splitting_the_data_directory) ## debug said bitcoind\_1 | 2023-05-25T03:55:17Z Checking all blk files are present… bitcoind\_1 | 2023-05-25T03:55:17Z Unable to open file /data/.bitcoin/blocks/blk00000.dat bitcoind\_1 | 2023-05-25T03:55:17Z : Error loading block database. bitcoind\_1 | Please restart with -reindex or -reindex-chainstate to recover. So I tried another method by editing ~/umbrel/app-data/bitcoin/data/bitcoin/bitcoin.conf to tweak blocksdir. #Load additional configuration file, relative to the data directory. includeconf=umbrel-bitcoin.conf blocksdir=mnt ## but debug said bitcoind\_1 | Error: Specified blocks directory “mnt” does not exist. ## or bitcoind\_1 | filesystem error: cannot create directories: Permission denied [/mnt/blocks] bitcoind\_1 | bitcoin in AppInit() bitcoind\_1 | bitcoind\_1 | bitcoind\_1 | bitcoind\_1 | \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* bitcoind\_1 | EXCEPTION: NSt10filesystem7\_\_cxx1116filesystem\_errorE bitcoind\_1 | filesystem error: cannot create directories: Permission denied [/mnt/blocks] bitcoind\_1 | bitcoin in AppInit() **I found out Umbrel on Rasberry only supports one drive, but Ubuntu version should support multiple drives, right? but I’m too dumb to find out how.** Is there anyone who succeeded in storing blk\*\*\*\*\*.dat and rev\*\*\*\*\*.dat in different drive? Please help me out. I mounted HDD to “blocks” folder but index folder is also trapped in HDD. I want to leave index folder in SSD for performance. If I make soft link for index, Umbrel debug said . bitcoind\_1 | 2023-05-25T19:45:59Z filesystem error: status: Symbolic link loop [/data/.bitcoin/blocks/index] bitcoind\_1 | 2023-05-25T19:45:59Z : Error opening block database. . I want to hodl my bitcoins rather than selling it for another SSD. ---

I did chmod and chown too, but it didn’t pass permission test. I think it’s an issue regarding docker, but I don’t know how to handle that. tried to mess with docker-compose.yml, but every attempt failed. ---

I found a workaround, that is to mount HDD to blocks folder and SSD to the index folder. (I found some people use a network folder for blocks folder but sometimes they failed cuz levelDB doesn’t go along with Samba.) 1. Create additional partition on SSD I tried to decrease one of 3 original partitions on SSD to create additional partition, but it leaded to fatal error to filesystem. I didn’t know how to fix it so I reinstalled Ubuntu. During reinstall I made 4 partitions, but Ubuntu was not installed on SSD due to the Logical Volume Manager of former Ubuntu. I had to remove 3 original partitions, create 1 whole partition, format that partition, and then **install new Ubuntu with 4 partitions**. LVM forced me to use a whole disk so I gave up using them, and just installed Ubuntu without LVM. /dev/sdc1 - BIOS boot /dev/sdc2 - mounted at / /dev/sdc3 - mounted at /boot **/dev/sdc4 - unmounted** 1. Install Umbrel and Bitcoin, then stop them curl -L [https://umbrel.sh](https://umbrel.sh) | bash ~/umbrel/scripts/app install bitcoin ~/umbrel/scripts/stop 2. Mount HDD to blocks folder **mount /dev/sdb1 ~/umbrel/app-data/bitcoin/data/blocks** 3. Mount SSD to index folder **mount /dev/sdc4 ~/umbrel/app-data/bitcoin/data/blocks/index** 4. Edit /etc/fstab echo “/dev/sdb1 ~/umbrel/app-data/bitcoin/data/bitcoin/blocks ext4 defaults 1 1” \>\> /etc/fstab echo “dev/sdc4 ~/umbrel/app-data/bitcoin/data/bitcoin/blocks/index ext4 defaults 1 1” \>\> /etc/fstab 5. It was a long journey for noob who uses Linux for the first time but I learned a lot through it. **One hard lesson is just use one 1TB or 2TB SSD**. I wish Umbrel support separating blocks directory from data directory at application level as Bitcoin core program does.
