Hi,
I have been running an glusterfs for a while, and everything
works just fine even after one node failure.. However, I went
for brick replacement due to my bricks were not thin-provisioned
and I wanted to use snapshots. In short, whole volume went down
due to heal daemon which tool all IO and all VMs running on top
of that volume started to be unresponsive.
In short, I am rebuilding the volume from scratch. I created new
thinly provisioned bricks:
lvs:
brick_s3-sata-10k vg_s3-sata-10k Vwi-aotz
931,25g s3-sata-10k_pool 2,95
s3-sata-10k_pool vg_s3-sata-10k twi-a-tz
931,25g
vgs:
vg_s3-sata-10k 1 3 0 wz--n- 931,51g 148,00m
df:
/dev/mapper/vg_s3--sata--10k-brick_s3--sata--10k 976009600
28383480 947626120 3% /gfs/s3-sata-10k
and mounted. When I uploaded two images onto it I found there
might be a problem. For the time being I run the volume in
replica 2 mode on top of two servers. The files were copied from
node1, and I think the files are OK on node1 only. However, the
volume heal indicates everything is OK.
Hi,
If I understand you correctly, are you saying that when you
created a new replica 2 volume with thin LVs for the bricks ,
mounted the volume (fuse?) and copied 2 files (VM images?) via
this mount, the files were being written to only node1?
Mounted by fuse.
I would not say written to only one node because both nodes contain
something, but I am quite suspicious about files on the node2.

symptoms are as follows:
