#find which mem chip exactly it is (in flashrom's internal naming scheme - the real chip is the 6406E, but flashrom combines it with the 6408E)
flashrom -L | grep MX25L
#read
flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=512 --chip MX25L6406E/MX25L6408E -r romread1.rom
#read a few times and compare with 'diff' to be sure read didn't have errors, just in case you have to flash back

Waltibaba / lxc_mount_block_device
Last active October 6, 2024 02:46
Mount a block device like HDD inside an LXC container (specifically in proxmox 4)
Mounting block device in lxc (specifically Proxmox 4)
1. Find devices' major & minor ID (need both dev + partition for HDD)
# ls -al /dev/sda
brw-rw---- 1 root disk 8, 0 Dec 19 11:16 /dev/sda1
# ls -al /dev/sda1
brw-rw---- 1 root disk 8, 1 Dec 19 11:16 /dev/sda1
That's 8,0 for sda and 8,1 for sda1

mysql buffer increase:
in /etc/mysql/my.cnf
-- innodb_buffer_pool_size=536870912 [512MB]
decrease root size by remapping /var/www/owncloud/data
this is the cache directory for uploads, that gets broken in every other patch, meaning loads of junk files there
map /var/www/owncloud/data -> /mnt/[nfs share]/dataroot to save space (soft symlink works)
OR
/var/www/owncloud/config/config.php
