Hi, I have squid 2.7STABLE9 running on Ubuntu 10.4 64it server edition. My cache is distributed between aufs and coss files on two separate disks I have coss on 250GB SSD running very fast...but from time to time I face problem with coss unable to read/write to this disk. Did anyone try to use SSD with COSS ? knowing the my SSD is formatted with ext4 Thank you.
