Description

In the EC2 AMI for 2.0, the data dir is on the large (100GB) EBS partition, but the server is given a symlink to it (underneath /var/lib/couchbase). When it reports the available disk space in the Disk Overview, it seems to report it based on the partition that the symlink is on, not the partition that the symlink dereferences to.

This appears to be preventing compaction, fyi.

Cannot compact view items/_design/all/main: the estimated necessary disk space is about 6668918434 bytes but the currently available disk space is 2113779712 bytes. (repeated 1 times) compaction_daemon000 ns_1@10.37.15.109 11:12:08 - Mon Dec 3, 2012

IMHO should be allowed for 2.0 given that it prevents compaction from happening

Added to RN as:

By default the image provided on Amazon EC2 of Couchbase Server may
incorrectly report disk free space in the Couchbase
Web Console. This occurs if your data directory is pointing to a symbolic link.

Updated in Release Notes:

In the past, if you used a symbolic link to reference a data directory for
Couchbase Server, when the server determined remaining free disk space, it
only found the free disk space for the partition that contained the symbolic link.
This resulted in two issues: 1) incorrect information in the
Couchbase Web Console, 2) more significantly, it would accidentally inhibit the
data compaction process because of incorrect information free disk space.
This has been fixed in 2.0.
