[Sol] inotify_add_watch … (No space left on device)
partitioning – inotify_add_watch — failed: “No space left on device” – Ask Ubuntu
inotify_add_watch(/home/xxxxxxx/.config/fcitx/dbus) failed: (No space left on device)
echo fs.inotify.max_user_watches=65536 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
Q：内核参数 fs.inotify.max_user_watches 的最大值？
A：AFAICT, root can change max_user_watches to any value that’s 2147483647 (231-1) or under, as long as you’re confident you have enough RAM to support that number of watches.
R：What is a reasonable amount of inotify watches with Linux? – Stack Overflow
