Fwd: slow start of zfs pool, rebuilding zfs-fuse from git

[Emmanuel Anne]

Here is the forward of the mail which couldn't reach the google groups for some reason, and the reply :

1) yes zfs-fuse doesn't like ctrl-c in the middle of these things. Well it will recover, but it will take time, just be patient, it can take more than 1 hour (i know it's stupid, I don't know if there is a safe way to interrupt this).

2) Compilation failure is probably because of libc6-dev-2.14 or higher. In debian testing we still have 2.13, so I'll stick with it for now ! ;-)

May I be so blunt to simply send it to you personally?

My mails seem not to get through on googlegroups.

pls forgive ...

Greets, Stefan

greets ...

following issue today:

I started a send/receive to "convert" a zfs-fs from uncompressed to
compressed.

That was slow ... so I decided to Ctrl-C that ... and issued a "zfs
destroy" on both the source snapshot and the target fs.

For both the system replied "in use" ... so I simply let that aside and
thought that sometimes later that would simply solve itself.

An hour later I decided to reboot the box due to another issue
(DVB-card, kernel-problem) ... after that the box booted up until the
start of the zfs-pool and mounting the zfs file systems.

And there it stood .... for an hour or so .... harddisks heavily working.

Was that to be expected?

I "solved" it by temporarily disconnecting the zfs-hdds, booting,
disabling zfs-fuse ... so that I could use the server again. Now those
fs are gone ...

Just to be up to date I tried to re-pull the latest release from
Emmanuel's repo (via my own gentoo-ebuild):

Here is a fix for the problem when compiling zfs-fuse with glibc 2.14.

It's committed in my repository (master branch).

As mentioned in the other thread (and fearing that my replies won't get
to the list *again*) I managed to patch the sources to compile with
glibc-2.15-r1 (gentoo-syntax).

Small fix, my guide was:
