What is wrong with fstab and where are my logs? Secrets /etc/messages?

Question

Debian

After installing proxmox in debian, I remounted @ data
it to a more convenient directory for me /pvedata.

# cat /etc/fstab
proc /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/md/0 /boot ext4 defaults 0 0

## /dev/md/1 belongs to LVM volume group 'pve'
/dev/pve/swap     swap         swap  defaults 0 0
/dev/pve/root     /            ext4  defaults 0 0
/dev/pve/vz       /var/lib/vz  ext4  defaults 0 0
/dev/pve/data     /pvedata     ext4  default 0 0

Since then, every reboot forced me to manually mount the partition again.
Yes, yes, when I published the question and "combed" the columns, which are not in the original
file, I found this huge mistake for attentiveness and, apparently, corrected
it. But still, it's kind of stupid. Where and how to look at the logs for such
errors, at the cost of a week of hemorrhoids?
This was the mysterious error in /etc/messages?

EXT4-fs (dm-0): warning:  maximal mount count reached, running e2fsck is recommended

Answer 1

O_o what is /etc/messages?
/var/log/kern.log includes dmesg output, mount error messages, and various hardware and kernel annoyances can be viewed there. If everything crashes during the download or work process, then you will most likely find the reason in this file. Although, not a fact, depending on how it falls.
This is the kernel log, debian manages this thing rsyslogd, the imklog module. You can customize as you like, if you put, for example, syslog-ng.

By the way, it mounts with this option))
